RE: Mt 57..... Runs like crap
I tried a 5 cell 6v pack and new plug, also by-passed ignition switch. No change. i don't think it's the ignition because it will sometimes run full throttle or 3/4 throttle without missing much or even at all. It's the lower rpm range that has a lot of gurgling/missing. Maybe miss fire is not the exact word.Perhaps itcould be something in the reed block area causing the problem. I checked the sensor and it seems to line up with the magnet.
I listened today to some you-tube videos ofother peoplesmt57. Mine does not run anywhere nearas smooth as the ones on the videos.
