What is the correct method?
The old timer that taught me always had me index the plugs and point the gap toward the intake valve. I have done that on N/A & Blower motors.
Is this incorrect amoung the world of engine builders out there?
I am having a hard time swollowing the part about just in cast the piston hits the plug. :?
I by no means am a rocket scientist, but if I have always used clay to check my valve to piston clearance and that also gives me a guide to the distance between the spark plug and piston. Even though math calculations seem to be correct, I have always check my clearances this way. "Just my little bit of self assurance"....
By the way that was an interesting read OneBad.
