Hi everybody. 80 400 special. Got starter and solenoid working great. Went to start it tho and hjad to have choke out full to start. If I let go of the choke it would die. Started it left choke out full for a while. Kept on throttle, let in choke. Kept running but I would hear pop coming from rightr pipe. let off throttle, it died? Any ideas? Could it be the carbs? Tx alot hav ea great day!
