cutting out on roundabouts

Post by monka » 30 Oct 2009 02:33 am

if i'm pushing it a bit round a roundabout my 340 is cutting out,

guessing it is due to the engine getting no fuel, but is this on the carb front or the tank, as i have put £20 quid of fuel in and it still does it.

1.7? Most probably carb float heights m8. For the love of god please check that the fuel return hose is still attached!!! Or your fuel will be leaking all over hot exhaust manifold :wink: Float heights should be 33mm but also weigh your floats to check they aren't leaking - they should be 6g

All my carb cars have done this, usually a symptom of fitting good tyres + good suspension. You want injection.

Not if you get the float heights sorted! My 1.7 coped on slicks on runways fine, but only if I'd sorted the carb out (and in the end the bloody thing started to wander, so it was a 6monthly job :()

But you want injection anyway ;)

Carbs are always a compromise - injection is smart.
