Re: Running on half choke
Pablo had a problem kind of like yours he sent me the carb and I found that the needle was not tapered right. and it was off by only 0.005.
I compaired his to my carbs needle with a mic. I reground it and the carb would then work properly. Before it would start and idle but would not rev up if you put on the choke it would try but would not work very well at all. after I tapered the needle it ran fine. at the top the needle miced 0.070 and at the bottom it miced 0.065 so its not a lot of taper and very hard to see the difference.
check out my carb post for the main jet size as I don't remember it right off
