the other day I decided to dig out the old and try and get it running again. it was sitting for the past 2 years. took the carb off and cleaned it out, replaced gas lines and filter, drained gas tank and put fresh gas in, new plugs. put it all back together got it to pop. started running for awhile and playing with the throttle and air adjustment screw. got it to idle and rev up fine. after awhile of running started to backfire out the carb at idle while giving it a little throttle. ive cleaned out the carb a couple more times and its still doing it. don't know what to do or check next. any help would be great.
