Head clearance

[NAMBA860]

Looking for help on a K/B drum rotor 3.5 inboard. I’m running 50% what should the head clearance be and what’s the best way to measure it?

Set the head clearance at .006

That's pushing it on the old gal.

0.010" be safe

Just use some small soft solder cut a piece the dia of the bore,and place it center across the piston /piston pin.
Or use a dial and zero out with the button on a flat even surface,get zero then replace button in engine and hand turn over engine with dial connected to button..
