  • So, maybe this is an ignition issue? slowly increase rpm, no knock, goose the throttle, and you get a knock? Is the advance working properly? You say you degreed the cam, but is the crank marker correct? Is the advance working smoothly when goosing the throttle? Is this a TB-IV ignition? Module could be doing funny things, or the pickup. Inspect the cap and rotor?
    Nope, don't run alky. not even 10%. I only use pure gasoline. Assuming timing is correct, I've found popping through the intake usually indicates a something going on with the valve train. I got here late and it's time for bed. If you want to chat, my cell is 269-277-2404. I'm on central time. Fred
