Re: G1 running concerns
Lean can make a 2 stroke bog some, its a bad idea because 2 strokes blow up when run lean. But this cart engine is pretty docile not likely to happen. Lean it usually will bog then take off, will run real smooth at part/low throttle where it should be missing and may surge. But lean is usually bog or bog initially then run fast, there is a line. Proper would be no bog and runs fast. Rich is misses a lot except at full throttle. A 2 stroke will actually run fastest lean but since fuel cools the piston they can melt a piston. Again a cart engine is low power so its not going to melt a piston very easily. A sled will do it in a heartbeat at WOT.
If the carb is clean and good fuel flow and airbox is together right, you should never have to change stock jetting.
