I have got a replica air cooled mini moto. Recently I have had a lot of problems with it, running ok for about 2 mins and then chucgging and diying. Then It will start and then die. I have recently changed the reeds, new plug, cleaned the carb, god knows how many times. Replaced some gaskets. Any ideas???

whats the ring like ,have you had a look at that????[ and the air filter ]

The ring is fine, but it was one of those old ones that restricted the flow of air getting into the carb. So I modified it a bit. But it doesn't seem to seal properly. But it seems to be running ok now. The fuel switch rubber had moved, a bit, is there anyway to bypass this, and the fuel going straight into the carb????

bloody thing is doing it again,,,,,,, it's driving me bannanas. I've changed almost evrything on the bloody thing. HELPPPPPPPPPPPPPPPPPPPPP

sounds like fuel ,or could be a air leak

I think it could be fuel aswell.
Try a pipe from the tank (fuel) straight into the carb without going through a tap or a filter.
Easy done and worth a try
Good luck

next time it does it ,take the plug outand see if its wet or dry ???? if its wet you might have a fault with the cdi unit!! It gives the same symptoms as a fuel fault......they start ok but when the unit starts to get warm it breaks down and causes miss fire farting etc

hey m8 check if there is a hole in the etrol cap so the petrol and takk can breath! sounds stupid but that what waz wrong wid mine and it cut out!

This post is over half a year old?? Like alot of the posts you have been replying to.
