Sorry if this has been answered already. I looked through some similar threads but couldnt figure out what my problem was.
I have a 48cc SD stinger engine that is causing the bike to jerk backwards and is making pops and cracks when I run it. At first, I had to hold the throttle in the "sweet spot" for the jerks to kick in, and once that happened the bike seemed to run smoothly. But now the bike jerks back and forth, running for 5-10 minutes at most before it putters out.
I've had head gasket issues in the past (mine is blown -- but I sealed it with steel epoxy and the head fits tight on the cylinder).
I was wondering if anyone knew what the issue might be. I've tried to run the bike a little lean but that hasnt helped either.
Also, I saw in another thread that there are five settings for the airjets on the carburetor, but I couldnt figure out where they are on my bike.
Any help would be appreciated, thanks.
