My needle valve had been sticking shut so I purchased a new needle, seat, & bowl gasket from my IH dealer. After installing the new needle & seat,no more sticking, the tractor ran very rich with more black exhaust than normal. I removed the bowl & it was nearly full of gas. My I&T book doesn't show a spec but the bottom toe of the float to the base of the top half of the carburetor measured 1 1/8". I changed it to 1 3/8" & got some improvement. I also measured both needles & found the new one is slightly shorter .025" than the old one. Does anyone know what the actual gas level should be in relation to top of the bowl? Sorry for the long post & thanks in advance. Sonny
