I got them locally at a motor factors will recheck the gap. Spoke to my dad tonight and he advised I need to have the vacuum hose to the distributor disconnected I had forgotten this step today. Every day is a school day with these old cars. Unfortunately for me this points and condensers is like new technology, by the time I did my apprenticeship as a mechie fitter this type of stuff was past. Enjoying the learning curve though.

Hi folks, unfortunately The spit didn’t make the show I did go along though there was some lovely cars 1 exceptional herald with revolution wheels. Anyway came home. Blew through the fuel line tank to pump but was spotless. I have rechecked the floats in the carbs ensuring they are 4.8mm from the top as per the triumph manual. Then on testing noticed that spark dropping off showing an intermitant spark at the plugs despite the inline tester showing a spark. As the plugs are brand new I have dugout the non ballasted coil and distributor with points and fitted. Car starts much better although likes more choke. Struggling to get the timing set seems to like it being 14deg btdc at least when I try to get it back to 10-12 the car stalls out. I haven’t done anything with the distributor (points and coil) spark appears to be very strong. Not sure if resetting the points is going to help. Notice the coil to be very hot also. Thought I would give everyone an update so far not out of the woods yet but think it has been a step in the right direction. And a big thankyou for all the help encouragement it is very much appreciated. Thankyou all.

Hi Pete, Yes I checked it after you had said looks to be correct. Positive from the ignition and neg to the dizzy. It has a ballasted coil fitted. Alan

Thankyou for the words of wisdom, will have a break tonight might get a look tomorrow if I get a chance. Was having a think and it is much worse when hot/warm. Reading a little on his accuspark and it says it can fail when hot causing the car to cut out. Wondering if I should splash out on an old fashioned distributor with points to rule it out. It has been fitted by the previous owner and it’s not the neatest. As when the car does stop it generally has to wait a while before it will start again. Starting to think I may have a few faults here! 🙈😂

So I have stripped the fuel pump, diaphragm is in good order. Found a lot of sediment sitting at the bottom of the pump so cleaned it all out. Rebuilt and tried to no avail. Will try blowing through the lines see if that helps. I have cleared the jets and cleaned the bowls. Looking like my show on Sunday will have to wait for another day! Thankyou again for the help folks.

Car was back together, running lovely on the drive reving freely after both jets were cleaned and blown through. Went a quick run made it 20seconds out the drive and it started playing up again aaaahhhhhh then died had to push the bugger home! Will have a check of the plugs next see what colour and adjust accordingly. At this point though I’m feeling a tad defeated! Lol 🙈😂

Disconnected the throttle linkage and tried each carb individually found the 1st carb to bog down and the 2nd revs no problem, have now removed the float bowl and jet and have them in my ultrasonic bath to clean them. The jet is brand new so hoping it will clear.

Hi folks, changed the dash pot oil for 20/50. Started the car still stalling out. Double checked my carbs are balanced. Will give another go with the mixture settings as I’m am sitting around 10 flats down from the bridge. Have only been tweaking it a flat either way. Plugs are very peelie wally not much colour to them. Hopefully it’s just a weak mixture. Unfortunately I have nothing at present to check the fuel pressure, I have new pump coming Monday just to rule that out but I’m not convinced that’s where the problem is. The engine is standard from what I know, the previous owner didn’t know either of any modifications choke is returning ok I have had a little bother with it but it is ok now. I have the timing at 10 deg btdc will maybe try advancing it slightly see if there is any improvement. When the car does stall out I normally whip the plugs out for a look and a clean regardless of whether the plugs have been sooted up, sure enough the car will start right up after this. Thankyou all for the help it really is appreciated.

So the 3 in 1 was something I had heard, however I can’t remember where or when I heard it haha will change it tomorrow! 🙈😂 when I say eventually probably a few seconds but depends on what I do with the throttle i can sometimes catch it before it dies and keep it running but only sometimes eventually it will stall. And at that point it’s a pain to start again. The mixture is rich according to the plugs as they were black and sooted up tonight. Gave them a clean and managed to fire it up again to make it the 600yards home before it died again. At that point I said screw it time for dram!

Will give that a try tomorrow. Thankyou fingers crossed.

Hi Johny yes both move freely. I have used 3in1 oil in the dash pots. Might try engine oil instead as I have read that the wrong oil can be an issue but not 100% on this.

I have a mk4 spitfire, starts and runs smoothly on the drive but under acceleration it bogs down and eventually cuts out. The car is fitted with accuspark electronic ignition and has a good spark. Compression test carried out and all are around 150psi. Timing has been set to 10degrees before tdc. The twin su’s have been stripped and rebuilt using a rebuild kit when running I have checked the butterfly shafts to ensure they are not passing. Jets have been set to 10 flats down from the bridge and both carbs balanced. New spark plugs fitted. There is a new inline fuel filter and I have removed and cleaned the mesh inside the fuel pump. Floats have been set and looks like a good fuel level in the chambers. But I still get bogging down when trying to drive. I’m running out of things to check. Any help would be appreciated. Frantically trying to get it sorted for a show on Sunday! 🙈😭😂
