Will do.

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.
Jets 70 Front 74 Rear
Powervalve 3.5 F/R
Pump shot 21 Front/22Rear

Once I get it to actually start and stay ideling I will tell you the rest.

the old plugs are for racing. Too cold for street use. idling etc. (use the champion RC12yc)
Ok thanks was wondering which plugs to use.
Carb venturii diameter (not the boosters) carb throttle bores diameter.
jetting. brand name of the metering blocks power valve vac rating.?
This is a little beyond my understanding,how do I measure these?
If this motor has a solid roller cam its a good idea to reset the valve lash.
I assume it is.
