Hi Tom, I was looking at the engine picture in your files and noted the nice vertical fan setup. The fly in this ointment can be the V-belt making 90 degree turns - like the Corvairs.
Over the years I had three Corvair Corsa 140s; they had very long V-belts which sometimes got thrown off on the overrun when you came off the throttle after some spirited acceleration.
If this problem occurs with your engine there is a fairly simple fix, and there is available (or was as of the last one I bought a few years ago) a spring-loaded Corvair idler kit for the right side middle pulley. This worked very well on Corvairs - when you come off of the gas the engine begins to slow faster than the fan and any belt "slop" (play) tends to occur between the fan pulley and the right side idler pulley - if the belt is a little loose it will jump off. The spring loaded idler pulley modification holds tension to the rear (eliminating slack) and keeps the belt from overriding the right hand idler pulley.
Of course you would have to modify a Corvair kit to work with your engine, but it should be fairly simple to do. Basicly the kit is simply a pivoting arm that holds the pulley and a fairly hefty spring from the arm to a rear mounting point on the body.
An added bonus is that with the right setup your fan belt is self-adjusting.
