For it to crank and run, the choke has to be used. The carburater has been removed many times by the macanic. He has a total of three old carbs, one of which was sent off to be rebuilted. He thinks the jet is not letting enough fuel thru. My thought is maybe it is the low octaine fuel (regular unleaded). This old tractor was built to run on leaded fuel. Has anyone had this problem before? The jet in all carbs look the same. My macanic rebuilt the engine and it runs like a top on deisel, just does not want to on gas. Thanks Ted

Do those carburetors have a main jet adjusment scr/w near the bottom of the carburetor? Your mechanic needs to open it by turning it CCW. Even my Toro mower and Wards garden tractor have that feature. Hal
