Hi, Just wondering if anyone could help me basically my vivacity 50cc will bog when i am setting off the line say at traffic lights, and it will do this until about 5/6 mph after which it seems to free up and it will start to accelerate really quickly. Now i am thinking that the low end is really rich so when it starts there is too much fuel going into the mixture which causes it to go slow. Now there are several screws on the card and i was wondering if anyone knew if these can be altered which will change the mixture setting ?? Thanks Jamie
thanks for the reply, i have been told it is running fine by a mechanic, he was looking at the spark plug colour. Do you know which screw is which ? I think there is three in total, one is right at the bottom one is sticking out with a spring on it and i can't quite remember what the other one is like but i am sure there is three. Thanks Jamie
thanks for the help, no the engine just sort of struggles but u can tell its too rich because it sometimes does it on a morning, but when the fuel tank is nearly empty it gets better. Somebody else has also told me to check the rollers to make sure they are not too worn, as it could be that, that is causing it to do it. But i am going to change the carb settings first, before i start messing about with the rollers.
