1989 SB50P Elite rebuild questions
Posted: Thu Nov 29, 2007 7:25 pm
I took a compression check and the results were 150 psi. I took the engine apart and the exhaust port was partially plugged. I then decided to install new rings. I now have two questions. The new rings that I purchased came with 3 rings. Two of them are identical to the old rings. The third ring is very thin, not much thicker than a piece of wire. When I removed the old rings I did not see anything resembling this thin ring. Where does this ring go, or is it a ring that is only used on some applications? My second question is should I hone the cylinder to get the old glaze off the cylinder. The cylinder has no scratches or gouges. I have always done this with 4 cycle rebuilds, but this is my first attempt at a two cycle rebuild. Thank you in advance for all replies
