My SR's not happy. I'm thinking its because of the cold and that I probably need a new fuel tank however see if anyone else has any ideas...
Re the fuel tank - it started to leak out the filler neck so I put a small rag at the top to catch fuel which stops the leaking out the filler neck but car started to play up from then on...
Car is manual choke running weber 32/34 with ram air filter. Car is a little jittery when cold and takes a while to warm up - likes to cut out when slowing down at traffic lights roundabouts etc - so I pull the choke out a bit more and it seems to recover.
However when temp gauge is "normal", choke in and driving along (variable speeds) it starts to judder and sounds like its misfiring. usually after about 15 mins of driving. It then starts to misfire badly and then dies altogether - its almost like theres no fuel getting through. I pull over, leave it a while, turn it over again - give it a good rev and after a few misfires it seems to clear what ever prob is. But its still not happy.
I thought it might be an air intake issue but theres no leaks in the manifold so I thought perhaps it could be too much air from the filter so in a bid to "bodge" something I cut the "nose" off an old bin lid filter and fitted it to the front of the air filter allowing warm air to feed to the carb. Also after advice restricted the air flow from the filter. I've changed dizzy cap and rotor arm which looked a little worn but still having issues. Theres no sludge and water isnt dropping (I know head isnt the issue). Its also not overheating and oil is fine.
I'm also going through fuel at a serious rate of knots - so far used 1/2 a tank and gone less that 120 miles! Its a 1.3!
I'm thinking theres debris in my tank thats somehow blocking the carbs jets or poor fuel flow - or too much fuel and its flooding - its just odd that it only really happens when the cars warm.
It has only just started doing it in the last month - when the temperature dropped and wondered if anyone had any ideas...
Ive ordered a new fuel tank anyway...
