So I was having some issues with my foreman not idling. I took the carburetor off and cleaned two jets; one was the drain and the other was kinda on the side. I made sure I counted the turns it was open before I took it out. The jet looked fine, but I blew air through it anyhow. The plunger seemed to work fine so I didn't fool with it. I hooked the carb back up, put all the connectors back on, but left the air breather off just to make sure it would run. I primed the carb a few times and it cranked right up and ran good, but it seemed that it would only run long enough to burn what was in the carb. I did that a few times, reving the engine some. It still wouldn't run very long and got harder to start. So I turned the jet a little that was on the bottom of carb to see if that would help. I hit the starter and it turned over but didn't sound right. I tried it again and it backfired. I tried it again and the motor wouldn't turn over. Then I tried the pullcord and it wouldn't turn the motor over. Did I blow the engine up or something??
