So today me and my bro were blasting the beach, and on the way back I was blasting over 50! Then, Bam! no compression.
Got it home, took it apart. Huge hole in the piston!
av7
70cc parma kit
g3 pipe
21mm phbg
42 pilot
needle on leanest setting
88main jet
Seems rich and plugs are black, so why the hole and not seizure? Picks to come in a bit.
Timing?
