Harry,
How many running hours do you think you are getting on the rubber Orings?
thanks,
Curt

I have used and still use an Oring on my 6hp Root&vanderVoort Triumph line.
The cylinder is slightly oval and it costs allot of $$$ to resleeve it. At 
my first attempt I used a big ring that would fit snug in the top groove of 
the piston. This was absolutle NO succes. Than I tried a thin ring that has 
some play on the bottom groove. It works great. The engine runs very nice! I 
show this engine a few times a year, and every year I put in a new ring. 
This is only 15 minutes work on an opencrank engine.

Harry
