JBrannon, I was looking at the length of the Briosn 52 and it looks like you would have to remove the carb cover and push the entire engine back until the carb was completly inside the fusalage and use the carb cover lugs to mount the engine. This may cause clearance problems with the rear exhaust. The distance from the firewall to the front of the cowl is right at 6 inches. The Brison is 8.4 inches long from the back of the carb cover.
It might still work but do some measuring before ordering the Brison 52.

Thanks
