The motor would run at 1/4 or 1/2 or 3/4 or full and then just die. Richening did last longer till it died. I leaned it, richened it at 1/4 increments with the same end result. Tightened the carb just a tad.
I just found hopefully the culprit. The smaller diameter fuel line from hsn to carb has a tear in it at the nipple. I'll have to pick some up tomorrow and try again, what diameter is the smaller?
