Does anyone know what the gap should be for 1999 HP500 carb engines? I just bought Denso Iridium plugs and want to get this right.
Thanks!

I figured they came pre-gapped. I was talking to I'CE today and he asked me what the gap was supposed to be - got me thinking. It turns out they were all at 0.35 already.
Now I have new plugs, wires, distributor caps and rotors. Looking for lost RPMs.
