Default Saito 82a vs 82b

Are there any significant differences between the Saito 82a and the 82b?

They run the same for the moving parts, cylinder, exhaust, and carb are the same.

The only thing different is the crankcase, back plate, and the stationary cam pivot shaft.

The 82B has the cam setting down inside the crankcase with a almost flat cover acrossd the top

The 82A has the cam within a cover that sits on top of the crancase.

It is the same cam in the same place - it is just a matter of how it looks to the eye.

The "A" version crankcase will break at the junction between the cylinder and cam box in a bad crash that catches on the cylinder,

I don't see that it makes a lot of difference for repairing crashed Saitos, one that hit that bad is pretty well done for anyway.

This all started with a redesign of the Saito 82 into becoming the FG-14 gasoline engine. The then went back and changed the 82 and 72 glow engines to have a crankcase like the FG-14. The crankcase is common between the 72 and 82 anyway except for the number on the side.

My Saito 100 has an almost flat cam cover with the major portion of the cam housing cast into the crankcase.

I have the 82a old style. Will the smae cam cover gaskets fit both the A and B models? I didn't see any parts for the old A model on Horizon.

They are different.

The cam cover gasket for the 91 will work on the 82A or you can cut your own.

It is important that the gasket be about .008" thick
