Was running great then ran out of gas. Put gas in it and it turns over but will not fire. When you open the petcocks fuel comes out. So I thought it was flooded drain the fuel then let it set for a night, done this repeatedly and still nothing. This has work before, it usually starts right up. I also need to know the part number for spark plugs and cross reference. Tractor serial number is 6u5308.:frusty:
