Just got my new 421 serval motor in the frame and im trying to break it in but im having some problems.
Its a 421 dune/play ported serval. I have pc pipes for now, 35mm pwks, k&n filters with outerwears, vforce 4 reeds,
With 35mm pwks i Started with 155main and 58 pilots with the needle on the 4th clip, im at 4000 feet. I synced the carbs and when i started it, It seemed rich and wouldnt idle. So i went down to 52 pilots which helped the smoking and it idles when its warm but not when cold.
Also the right cylinder smokes and pops a little. It has a chariot racing cool head so i know the o rings could be off. Not sure if compression testing would tell me much since i havent broken it in yet.
Also when I was syncing the carbs i noticed a little smoke came out of the carb on the right side
