Hi
Can any one tell me that if i change the piston ring for a glow engine should I need to breaking in the engine again r just installed in the model n fly.
Plz suggest me
It is a very good idea. One of the main purposes of breaking in a new engine is the controlled "bedding-in" or "wearing-in" of the pistong ring with liner. In your case the liner has not been changed, so you can do a reduced break-in
If you change both ring and liner, you should do the whole breaking-in process again
Hi Sanjay, thank u for the suggestion, will do that
