Start by getting new spark plugs Champion RC12YC gap at .035"

carb jetting.... timing at idle, manifold vacuum at idle,,, idl speed (rpm)
Timing at max advance...
carb power valve rating. Is it blown? reduce the fuel pressure to 6psi at idle.

the old plugs are for racing. Too cold for street use. idling etc. (use the champion RC12yc)

Carb venturii diameter (not the boosters) carb throttle bores diameter.
jetting. brand name of the metering blocks power valve vac rating.?

If this motor has a solid roller cam its a good idea to reset the valve lash.
