Final Assembly
Fuel:
We recommend using 89/91 octane pump gas as these engines run
well and tune easily with it. Higher octane race gas, besides being illegal,
usually requires the timing to be advanced and carburetor to be leaned out to
tune properly which in turn makes the engine run hotter and does not show an
increase in power over the pump gas.
Mounting:
(1)
We recommend the use of a 15° angle mount. This increases the flow of
air to the cylinder head and also creates a “sump” for the oil to collect in.
(2)
Fuel filter should be mounted low (on the frame rail) and near the gas
tank
