So, it seems #125 is not right. With all stated parts. Started right up, then took it for a spin, first thing I noticed was terrible acceleration. I had better before. Then full throttle was worse and heard small backfiring and a few "hiccups" from possible the air intake. Before going with new main jet I completely closed air/fuel mixture screw and did a few turn in increments of 1/4. Adjusted the idle screw. All this after letting engine idle for 10min. Tomorrow plan to drop it to #120. Tomorrow will measure what size was in it and may find I shouldn't have messed with it. Did I miss any other adjustments?
