When it's at a low idle it runs fine and when it's at a high idle you can tell it revs up and down but when you drive it especially going up a hill or pulling something it is very bad revving up and down so bad that it jerks you any idea what thus could be I adjusted the carb and got it runnIng smooth when it idles but same thing when I start going any idea ?

My Super C surges when at full throttle, slightly, but under a load and at low idle is smooth as silk. When I first brought it home it would spit, hunt, surge, had a misfire about every three revolutions, and was worse with a load. I found loose spark plugs, and a bad gasket at the carb.
