Thanks for the pointers el lobo. I will try to work on the choke to see if I can make it better. That seems logical since it is mostly a problem when it is cold. I am still confused though, because it used to start right up and I haven't changed anything.
A few of things come to mind:
> 1.too much fuel/not enough air = a very rich condition causing your black
> plugs and smoke.
> 2. Jetted properly? Someone may have altered or replaced them.
> 3. Air cleaner clean and not too small to breath?
> 4.Choke not adjusted properly. Should be part way open on cold start, then
> fully open when up to operating temp.
> 5. Once you get it running right, I would put some carbon cleaner in the
> tank and through the carb to clean the upper chambers of the carbon build > up.
> Good luck and let us know the final results.
