I have been trying to get this lift started for a few hours. The only time I can get it going is if I spray carb cleaner in the air intake. but it only runs at high idle. when I try adjusting it at the carburetor it dies out if I get the idle down to where it sounds good. I have rebuilt the carburetor, and replaced gasgets where I found leeks. I've chased the feul to see If its clogged somewere. there was a hose clogged on the (water/fuel filter thing) but that didn't fix the problem. soo it seems to me to have a heavy leak allowing air into the system so their is not enough vacuumed fuel. not sure that any of this made sense. please help
