I have a 2000 Rancher that I had at the lease. Got to the very back of lease and rancher died. Could not get it started. When turning over it would back fire like a 22 rifle. After about 10 minutes it would start and run ruff. Could only go about 3mph for about 2 minutes then die again.

When I got the Rancher in the truck noticed a steady stream of gas coming out the overflow tube. Pretty sure carb needs a good cleaning. Do I need to replace the vacuum diaphragm? Also how can I get the float valve seat out, or do they come out?
