Got motor for free but took motor apart and there was little scratches on pistion everthing else looks cherry also discoverd there was no shims in the motor need help where i can get parts motor also has very cery very good compression but only will run for 4 mintues and shuts off..... would like to hear your 2 cents thanks

It's made by Novarossi so parts for the same model Novarossi motor are the same.

Are you sure it doesn't have any head shims? They are aluminum and stick to the head sometimes and it looks like there are none.

What motor is it it similar to and also there was no shims motor had no show of Detonation piston was smooth and head Button was smooth... im meaun smooth as a babies butt
