Adrian Posted April 24, 2021 Report Share Posted April 24, 2021 Hi all, due to one thing and another the car hasn’t moved for a couple of years. Fired it up last weekend and eventually woke upon the choke. Thing is it just doesn’t want to keep going. Got it to start warming up but dies when the choke is off. Was running fine before. Should I put a gallon of fresh in the tank or could it be something else. cheers Adrian Link to comment Share on other sites More sharing options...
Badwolf Posted April 24, 2021 Report Share Posted April 24, 2021 Sounds just like the problem that I had last week. Started on choke, mis fired, jumped, stalled, died until warm then ran lovely. Never thought about the fuel being stale. Tank is showing half full so plenty of space for the whiz bang bit to have evaporated?? Hummm!! Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 24, 2021 Report Share Posted April 24, 2021 Ive not left a car for 2 yrs but general witer lay ups it starts on the button old fuel can attach a lot of crude to the needles i have just refurbed some off the road 30 yrs strombergs and you needs a gorilla to get the needles out of the jets and they were when cleaned up corroded to the extreme no signs of fuel in the floats all quite clean but it simple the pull a piston and give the needles a clean without upsetting anything Pete Link to comment Share on other sites More sharing options...
Nigel Clark Posted April 24, 2021 Report Share Posted April 24, 2021 Very likely to be a fuel problem. I recommissioned my old Triumph 650 bike a few months ago. It had been standing for 2 years. The inside of the carb was full of solid deposits and the fuel in the tank smelled like varnish. I stripped and cleaned the carb, put fresh fuel in the tank and it was fine. Modern fuel doesn't last, especially when exposed to air and/or moisture. Nigel 1 Link to comment Share on other sites More sharing options...
PeteH Posted April 25, 2021 Report Share Posted April 25, 2021 I could have posted to this effect before. But I had an issue with a 2.3Kw 4 stroke Generator, not / being difficult starting after a period of non use. Speaking to the Supplier as it was still warranted. I was advised to try removing and replacing the Fuel and cleaning the Carburator?. This did in fact work and the Genset started first pull. I now drain down completely before storage and use fresh fuel. The old fuel goes in the "daily". The explanation being that EN5%? (Ethanol) fuel degrades in storage and can/does affect starting. I am advised that because of this, the Ethanol is added to the tankers as they are filling at the refinery and not to the storage Tanks.? It is also becoming an issue with Garden Machinery after winter storage too. Pete Link to comment Share on other sites More sharing options...
Badwolf Posted April 25, 2021 Report Share Posted April 25, 2021 When I changed my fuel filter the other week, I was appalled at the amount of crud in it. The inside looked like it had been varnished. Also had trouble with the lawn mower this time last year. Eventually I just filled the tank and left it to soak. It ran fine after that (the mower that is), but have that enjoyment to come yet. No grass due to mini wolf's antics on what used to be the lawn.

Adrian Posted April 27, 2021 Author Report Share Posted April 27, 2021 Thanks for the comments as always uncle Pete came up trumps. Fortunately only a slight varnish on the needles, quick spray and wipe with carb cleaner and tentatively holds its own now. I’m guessing it’s the old fuel that is causing the lower than expected running. Video is it running at temperature, note the struggle when revs drop. so can adding fresh fuel clear the varnish from the system (I have a sealed Jerry can, would the fuel be fresh in that?). The tank is just below half full. cheers Adrian IMG_2876.MOV Link to comment Share on other sites More sharing options...

The tank is just below half full. I bought a Kawasaki bike, that been standing for quite a while without the carbs drained. Couldn't set it up well. After a good few hundred miles of running with fresh fuel it seemed to sort itself out?. This was before Ethanol, though varnished carbs apparently could be an issue. Used to be a practice of soaking carb parts/bodies in cellulose thinners for a few days?. Link to comment Share on other sites More sharing options...
Colin Lindsay Posted April 27, 2021 Report Share Posted April 27, 2021 What about 50% Redex in some fresh petrol, run that through it - it should clear the carbs nicely. Link to comment Share on other sites More sharing options...
Peter Truman Posted April 27, 2021 Report Share Posted April 27, 2021 I've found Carby Clean a very effective cleaner don't know if it affects varnish, I use a local product called "Fuel Doctor" to keep the fuel fresh and keep the tank & fuel system clean, its produced by a Co that professionally clean and protect garage storage tanks.

Yes, Well. Redex? theres a blast from the past, Dad, would put an eggcup full in each cylinder, leave for an hour or two, then turn it over on the handle and run the old Hilman to clear the Carbon. Huge clouds of smoke! "we" used to go on Humber Bank to do it, away from society. Pete Link to comment Share on other sites More sharing options...
Badwolf Posted April 28, 2021 Report Share Posted April 28, 2021 Redex! Never thought of that and I'm sure that I have a bottle somewhere. Does it go off with age? It must have been there for about 4 years. I think I got it when I recommissioned the car a couple of years ago. By the way, what is in Redex and has it changed since my Dad put a squirt of Redex per gallon in his car, back in the 60s? (By the way, before somebody else thinks of it, the answer to the question "What is Redex?" is not "It is Red" (with apologies to Data in the Star Trek Next Generation episode - Relics)) Link to comment Share on other sites More sharing options...
Colin Lindsay Posted April 28, 2021 Report Share Posted April 28, 2021 Tesco sold it very cheaply a while ago, about £2 per bottle. I use it on all my older engines. Fill the tank, drop half a bottle in, and whatever it does the engine keeps on running. Link to comment Share on other sites More sharing options...

Adrian Posted April 28, 2021 Author Report Share Posted April 28, 2021 Hmmm. Got an old bottle on the shelf from when I had my first car. Vauxhall cavalier! Soooo as badwolf said shelf life, would 30 yrs old still be OK? If not, why on earth do I keep stuff like this, before I know it I'll be collecting bent nails in a jar to re-use like my Dad did....and never used!

I know. But I have a half full jar of terminally rusty 1-1/2" Panel pins. Courtesy of the Father in law, from when we cleared out when he died. Like above, I think there could be some Red-Ex living on a shelf somewhere!. Pete Link to comment Share on other sites More sharing options...
Badwolf Posted April 29, 2021 Report Share Posted April 29, 2021 Talking of fuel and oomph, the cross over thread here.. https://forum.tssc.org.uk/topic/8045-my-2500-allergic-to-unleaded/?tab=comments#comment-113538 also raises a comple of points including my enquiry about bulk petrol storage. Adrian - The use of the 'word' oomph in the title is clever. 00 (zero) mph. I like that. Link to comment Share on other sites More sharing options...
Peter Truman Posted April 29, 2021 Report Share Posted April 29, 2021 Talk about clearing out houses when Dads old Sec had to go into an aged care home I had to clean her house out, she was like a big sister to me only about 15 years older than me and when I was growing up I think she attended more teacher parent interviews than my parents who were always away. She was with dad for about 40 years in England, Canada, Australia, England, Canada, USA, England and retired back here in Aus with the parents, she had kept her Aussie house from her first stint here. Her Australian husband was a pilot with the RAF flying Spitfires, after one sortie his plane was so badly shot up he had to ditch into the English Channel, it was a couple of hours before he was rescued, unfortunately it really affected him and he would never talk about his experiences, he was heavily decorated and as an Aussie pilot with the RAF he was fortunate enough to be selected to spend a weekend with Churchill at Chequers Anyway whilst clearing out the garage I sourced a lot of fantastic tools her very hands on DIY husband had acquired thro his engineering life, but I found this Macintosh 10in dia tin full of what looked like Starter Gun Caps, but in reality they were detonator caps used on the railway to warn working crews of coming trains they were put on the tracks and exploded when the train ran over them. There would have been a couple thousand caps in the rusty old tin so I took them to the nearest police station to hand them in, they weren't keen on taking them, so I rang my close friend ( and fellow Triumph fan) who was the very senior officer in charge of the SE suburbs of Melb told him what I had then handed the phone to the unhelpful policeman over the counter you could hear the spray from 100 feet away, so I departed quickly without tin before they could think of something to book me with!

Adrian Posted June 2, 2021 Author Report Share Posted June 2, 2021 Hi Chaps Took your advice this evening drove to shell for some 99Ron V power. Had 1/4 of a tank of old fuel left put £45 of fresh in. Had trouble from the very start getting going and just got in from 2 1/2 hrs, 1/2 mile from the garage broken down. Very lumpy, uneven running and absolutely no pulling power, could not move as on a slight upward incline which seems to make it worse so not sure about going to a car show this weekend, or indeed anywhere at the moment. Maybe you can help with a bit more diagnostics....basically I was able to get home after waiting endlessly for the RAC who didn't arrive by which time it had cooled down and ran much better, but still as it got hotter (the temperature was normal) I could feel it starting to slip away again. Any ideas or do I admit defeat and take it to the garage? Cheers Adrian Link to comment Share on other sites More sharing options...

I had the same on a Wolseley once it took ages to sort out as someone had put two filters on it and the one i could see looked clean. Tony.

JohnD Posted June 3, 2021 Report Share Posted June 3, 2021 You clearly have a bad misfire. That it ran better when cooled down, and your previous post (Apr 27) when you commented on "running at temperature, note the struggle when revs drop", makes me think of an electrical fault, when hot. Resistance usually rises with temperature. Check the low tension ignition wiring and connections, and the state of the dizzy, esp. the carbon contact in the cover, but the coil may be failing when it gets hot. Triumph mounted them on the engine block, never a good position for a temp sensitive device! Mounting it on the bulkhead needs only a longer 'king' HT lead, and will keep it cooler.

Pete Lewis Posted June 3, 2021 Report Share Posted June 3, 2021 the ffact its the first time you have filled the tank makes me think of upsetting the debris do check the coil is wired neg to dizzy pos to ign feed there was some thought the coil was block mounted to act as a cooling heat sink or was it just the way the engine line tested the unit ... needs a canley ghost Pete Link to comment Share on other sites More sharing options...
