Does anyone know of an easy way to remove carbon from the exhaust port of a 4 stroke? There is a fairly thick layer in there and I wanted to get rid of it before I put the engine back in the frame. Any ideas at all?
The top end is still together so if I scraped at it wouldnt there be a chance that some of the stuff would get into the cylinder? What if i made sure the exhaust valve was closed, scraped at it then took compressed air to blow all of it out. Would that work
