Re: 28mm carby suitable?
28imb would probably the best way to go, my 595cc engine in mine does great on that type, theres no re-jetting required as far as i know.

So just put in a 595cc with 28imb carb and I have this faint black smoke going on . Is this a fuel air mixture issue or should I change out Carbs.Oh and did I mention that I have a new motor because I dropped a washer change carbs in the old one so my knowledge is very limited.
There are usually three types of visible 'smoke' emitted from exhausts - all suggest problems.
Blue smoke = oil in the mixture. Usually from a worn engine with oil either getting down past the valve guides or up past the rings.
White smoke = either brake fluid in cars fitted with vacuum assistance (split diaphragm) or water (steam) entering via a leaking head gasket. Neither can happen in these cars as the brakes are not vacuum assisted and the engines are air cooled.
Black smoke = unburned fuel. Results in the engine running rich and is usually due to misadjustment of the carby - mixture incorrectly set, float not correct, wrong jets etc. A faulty fuel pump can also do this.
If the exhaust smells of petrol and you are blowing black smoke, check the carby first. It may just need a minor adjustment.
