Just rebuilt a Vespa PX 200 engine.
I have two spare O-rings left over and it's vexing me if they need to go somewhere. Are they just leftovers? They are slightly smaller than the ones on the rear brake cam shaft.
Anyone know?
Cheers Gary

Could they be for the clutch arm?

I did think that Shaun but they may be a little small for it. Anyway I did them recently and don't want to take the stiff spring off again in a hurry :D

There should be two on the brake peg castings behind the brake backplate.

If you've done the clutch arm, kickstart, backing plate and brake cam there's nothing left on the engine.
Is the front brake cam slightly smaller than the back, could b for there. I'm not sure but there maybe diffrent size brake cams depending on year of px.
I seem to remember having left overs
