ground was ok and flywheel key is ok. so i took the reed cage out. and there is two pieces. i took the screws out ,took 1 piece of plastic off then took the reed off in the middle of the bottom edge its burnt black like half way threw , this isnt normal right.. could this be from when i cold siezed. also checked compression could only get 65 could bad reeds cause low compression since its a new top end?
