ENGINE FLUSHING

Generally yes its a good idea to take a look inside , parts id particularly look at are

Cylinder , pop off the head look inside , piston to bdc , flush to exhaust port
Crank case , check for any debris etc ,

Re oil with Parrafin or MMARF oil or Singer Oil

Having said that i pull apart go engines every day and are still to find any debris , they go through a very strict QC and cleaning regiment at the factory before assembly. When i inspected the Assembly room at the factory i had to take off my shoes and put on a hair net, surgical slippers etc , it was like i was about to go into surgery !

BUT still i always check just in case .
