Re: Tune up (or what?) Suggestions...
If you've got black exhaust there is no question that the carb is way rich.If it's definitely not the choke,then the next thing to check is the float and the needle valve that it controls. I'd say that is 95% chance of fixing it. NOT a difficult procedure at all.
>>Of course if you are running with a totally loaded up air-cleaner you may get the same black smoke.
