It's the smaller one Harley.......... I think I have finally gotten it running. I changed out the power valve and that stopped the gas from dripping into the carb and now it seems to be doing fine. I am not too optimistic though since when the last guy rebuilt it, it was running great too and then all of a sudden it messed up......... I probably need to splurge and send the thing off to Pony Carbs this winter and get it fixed once and for all...........
