Thanks T,

Actually, the ST and the Saito are the same weight, 31oz. The Moki is 45oz.

I'm going to go ahead and try the ST and see how it does. If it is just too slow I will buy a Mark. I mounted the ST today and it is a good fit with a Pitts muffler. I will probably need a pump to make it run properly with the low sitting tank but we shall see. I'll keep you posted.

Blessings, Terry
