Take the motor out of the equation to begin with.

Set the mesh of the clutch to maingear as it should be and with the clutch assembly running parallel to the mainshaft.

The design of the gasser gives you fewer options for shimming and the like than the glo powered models provide. What you can do is slightly enlarge/elongate the front holes in the frame to position the motor as needed. Leave the rear mounting brace alone until you get the motor in the right place. You can then go back and elongate the back holes in the aft direction if the motor needed to be shifted backwards or simple place some shim washers under the gold plate between that plate and the cylinder head if the motor ended up having to be shifted forward a little.

These ideas have been used by individuals in the past who have installed modified Hanson engines and needed to change gear ratios to provide optimum running rpm ont he motor.

Remember; if the fan won't line up squarely to the cluch face in the stock postion, the solution is NOT to try to tilt/pivot the engine fore or aft. You need to move the entire engine fore or aft in the purely horizontal plane to get in in squarely.

Does this help some?
