Honda CG125 carb setting advice please.

[Guest]

I have a 1979 Honda CG125. Running ok but spark plug quite sutty which suggests running rich.

I have set the air/fuel mixture screw to two and a half turns out. If I set it any less out i.e. making the mixture leaner,

the bike pops/misfires on acceleration. Is the existing (rich) setting ok or could anybody please suggest any other options?

Any advice is much appreciated.

Thanks.

this question may be better placed in the "pit stop" section of the forum.

apart from that, sorry i cant help you out.

How clean is your air filter?

I agree with the air filter question above. The idle mixture will only adjust the mixture at idle......the mixture above that is controlled by the main jet. Needle height should be checked as this can affect the running of the bike....make sure the needle is in the correct slot.

The float set too high will also let more fuel through than it should - I think?
