Never built one, but I would think there would be an advantage to keep the center of gravity as low as possible. If the carb is pitched down some, it would run more level when pulling, or when the front end rises. I'd keep the engine low.

The ones we have built we set the front of the crankshaft at 13 inches. Have had good luck that way.

Four degrees should put you in the ballpark, but understand the height at the crankshaft nose is relative to the forward placement of the motor on the wheelbase. Pinion angle is important. JW
