I took my moped out for a ride and things are OK ... until the engine started making funny pop-pop sounds and bits of blue smoke. Do I have a dry gas perhaps? Or is it something else?
I cleaned the carburator yesterday and so that's not the problem. But perhaps I have dry gas? I'll drain the tank and get new gas for it.
I don't think I'm running lean/rich, since I have the same mix as before. But the gas is from about 2 months ago ... even though I just added some (but also from 1+ month ago in a gas can). I put the carburator back together properly and everything was fine last night. The engine actually hummed at a high pitch and seemed to go very fast (no speedometer). I have no idle now, but that's a problem w/ the throttle grip and shoudl not be related to the muffler sounds.
Could I have a seal loose somewhere? The popping seems to come from the front of the muffler, not the back. But I was riding in the rain, and so my hearing may have tricked me. Maybe just water in the carburator?
But any other suggestions of things to look for would be greatly appreciated. I think she'll get me home this evening ...
