They do not come greased almost at all, seen several failures on the cams on ready .
When you adjust the valves....make sure you go on the same cylinder 3 THREE times before you move to the next.
It has 3 sets of cams inside and I think they machined not quite the same.
If you adjust one and you see it is good and all OK then you have all the chances to find it to sloppy to the other cam set or to tight...you may need to find a happy medium.
Had several trough my hands and looks that all do the same thing.

thx for the warning Adrian! but im a little confused (this engine is new to me)....what kind of "grease" - like axle or wheel bearing grease? isn't the cam sitting in the crankcase where the fuel/oil mix goes? those brass cam followers are where we are told to add after run oil for the engine. wouldn't grease be diluted by the fuel mix and contaminate the fuel mix going into the combustion chambers?
.
also, as a side note, do I need to add some kind of sealant between the OS carb and the adapter? the stock o-ring fits between the adapter and crankcase backplate for a 'seal', but I didn't see any kind of seal between the adapter and carb - is it needed?
