Hi Alan
Thanks for the help i have been in contact with fly engines to price the parts because i still cant get walkerjet but i have attached a few pics of the engine i have broken it down and i would love to hear your view as to what may have caused this problem . All the damage seems to be on the exhaust side of the piston and cylinder ,Im not sure but anyone that understands two stroke engines will know this means something hope you can help
regards
Iain
