Guys,I'm trying to get my saito to run properly in my ultimate and am having fits.This is my third 1.80 and most problematic to date.Starts,runs,slows down and quits.I've already turned the carb around so its in line with the tank,messed with the high speed needle and nothing.I'm starting to think that the small cowl openings in the front may not be large enough and is causing the engine to overheat.Did anyone have to close off the opposite side opening?Thats my next step after I try running it with the cowl off.If anyone out there has this combo let me know how you made out.

Thanks
