Oh, All worked out well with the 21-7 fms today. Piston and sleeve looks great. I lucked out, when I pulled the 97t yesterday the fillament was barely hanging on. I disassemled it today, all looked good. Reinstalled it in the truggy today with a new c5tg nova plug and all was well. Monty I leaned the LSN almost a 1/4 turn and the HSN about 2 hrs. I new I was running rich but wanted to make sure I had plenty of fuel for the first 1/2 to 3/4 gallons and man this thing has power from top to bottom for a .21. My temps are now running around 235-240. Are these temps still in the safe for this engine. I still have a little smoke from bottom through the mid.
