  1. Spot on. Blew out the float valves and pumped a bit of petrol through and it stopped leaking. I think I need wing nuts on the float bowl screws.. Previously when I had needle valve problems the petrol came out of the front of the carb mouths. I had replaced the needle valves a couple of weeks ago after having the rubber slivers from changing the fuel hoses. I wonder if the new needle float valves were sticking.
  2. So i've checked again. It's not coming from the link pipe but from somewhere in the choke mechanism or choke spindle. It floods out when the float chambers are full. I'll check again the needle vale but that normally causes petrol to come out the front of the carb.
  3. Yes that's where it's coming from. I'll go and have another look
  4. So came back in the gt6 smelling a bit of petrol. Lifted the bonnet when I got home and sure enough petrol dripping from the bottom of the air filter. No problem I thought must be sticking float needle valve I'll just whip the float chambers off. However, when I finished and restarted I saw petrol pouring from the front carb. However, not from the front of the carb as it does when the needle valve leaks but from the side of the carb, the side facing the rear carb. How comprehensive are the rebuild kits and any ideas of the leak? Half tempted to go for SUs or triple webers.
  5. Ok, so knocking noise solved. Started her up and getting regular noise again , tiny bit worried it was a small end. Rocker cover off , no noise and tappets sound perfectly adjusted since I double checked them. Rocker cover back on with engine running , no noise. Tighten bolts slightly and no noise. Tighten middle bolt up to torque and noise starts. Can slightly feel a tap. So undo but half a turn and noise goes away. So it was the Rocker cover slightly contacting a tappet. Not hard enough to mark it though . Sorted!
  6. It's a tin cover but I might have tightened it down more than it was before. Will try the feeler guage
  7. So my gt6 engine has finished running in and one of my winter jobs was to re-torque the head. I did this and then re-set the valve clearances. On start up I heard a slight tapping/knocking sound. It hadn't been doing this before so I thought maybe I did a valve clearance incorrectly, or maybe missed one. So, off with the rocker cover again and re-doing the clearances. Maybe one was a tiny bit out - say 12 thou instead of 10 but nothing much. I started the engine with the rocker cover off and no noise. So I thought must have been the clearance. Put the cover back on and I can hear the tap/knock again. Took it to the shops to get essentials and gave it full throttle in second when warm and it sounded silky smooth from within the car. Yet in the garage I can hear this slight knock at tickover. Any thoughts?
  8. All done on both carbs and no leaks any more. Would be nice to replace the float needle valves at some stage. Float chambers were surprisingly clean with fuel and just a couple of black rubber slivers in the one nearest the bulkhead. Just got to redo the valve clearances and change the oil and she's good for a summer of reversing in and out of the garage. I've just worked out that the only mechanical parts, including engine, radiator, exhaust, propshaft, suspension , brakes, CV joint replacement and diff that I haven't replaced over the last three years is the gearbox. I never intended to replace everything it just happened.
  9. Taken the float bowl off the carb that had petrol pouring out. It was the one furthest fromthe fuel intake at the gearbox end so it might have been slivers from the hose between the two carbs. There were some black bit in the fuel bowl. The cut off pin was also stuck. As soon as I pulled it it started moving freely. When I pushed it up it cut off fuel from me fiddling with the pump and when I let go fuel poured out. If I put it back together again is it likely to get stuck again? It seems to move freely now. Can you buy replacements? Any I'll let all the petrol dry up put it back together tomorrow and give it a lash.
  10. Thanks guys too help as ever. Will report back
  11. Nothing coming from the bottom of the carbs either so must be out of the mouth of the carbs
  12. I've just replaced all the fuel hose in the gt6 with nice club sourced ethanol resistant stuff. Just started her up and there was a flood of fuel coming out of the bottom of the standard air filter. Nothing coming out of the new hoses. I tried tapping the side of the carbs in case it was sticking needles in the float chambers. I've never taken Stromberg's apart so any suggestions for diagnosis and fix?
  13. I would think he would probably restrict socialising anyway. As the rest of the world is shutting bars, restuarents and clubs I can't imagine we are that far behind.
  14. Thanks, will do it now before it comes out of hibernaton.
  15. I've just done 500 ish miles on my rebuilt engine and i'm wondering whether to re-torque the head or not. I know this used to be the done thing but have read that it's not necessary. Should I do it? Half of me thinks disturbing something that doesn't need disturbing might be more harm than good.
  16. I'm just replacing all the fuel hoses on the gt6 with ethanol resistant hoses. From the end of the solid pipe as it enters the engine bay to the fuel pump I want to put in an inline filter before the fuel pump. I'm not sure whether to use on of the glass ones, or one of the cheap plastic ones. As I see it the glass ones have rubber o ring seals so those would have to be ethanol resistant whilst the plastic one have paper elements. Any thoughts?
  17. Just checked and there is no rubber seal, or any seal, on the radiator cap so it wouldnt suck anything back. Assuming that's the problem.
  18. I'm going to get the wednesday overnight ferry from Portsmouth to St. Malo. I'm parking in the club parking with the gt6 but will only stay a night or two and then head further into Brittany to my house. Not having been before, is it ok to leave the parking half way through the event?
  19. One of the winter jobs I want to do is replace the current rubber fuel hose with ethanol resistant stuff. Does anyone know the internal diameters I need to order. I know I could go and measure but i'm sure you clever people know it off pat. From memory there is rubber from the tank to solid pipe, I think from the solid pipe to the fuel pump, then from the fuel pump to the carbs, then between the carbs. Is it all the same diameter? Thanks in advance.
  20. So i've just run in my rebuilt 2.0 litre engine, or at least got it to the stage where I need to re-torque the head down after a couple of hundred miles. The only thing wrong at all with the car now is that I am losing water into the overflow bottle. There is no oil in the water it is still clear blue water/antifreeze. There is no water/mayo in the oil. So is this likely to be a weak spring on radiator cap. It is a new one but seems really easy to squeeze together or maybe pressurisation from a head gasket? The car runs at the same temperature as ever before and doesn't overheat.
  21. Well i've just booked tickets through the club for classic le mans. It will be my first club event despite having been a member for 5 years and having Triumph's on and off since the '80s. I'll be getting the overnight wednesday ferry to st malo but only be staying for a couple of days at Le Mans as i've got to go to my house in Brittany on the friday night . Really looking forward to the event.
  22. Very sad. mark is a great guy and I hope his health improves.
  23. Thanks. Good suggestion. Will report back
  24. Thanks but if I can't get a socket on the crank nut how do i turn the engine even with the plugs out?
