This may not be an ARF question, but I know a lot of the group is equipping ARF's with Saito's. I have a .72 that the intake o-ring keeps backing out of, and leaning the engine out until it doesn't run. Is this a common problem with this engine? It's extremely annoying. The little .30 I have has a flange that keeps it tight to the cylinder, the .72 just has a groove it seems to slip by. Looks like a design issue, any good cures for this one?


Thanks.
