Some folks say to use a match book cover... about 0.25.

I don't know the real answer, but you do need a gap and this gap will
affect performance.

A match book or bussiness card is just about right

BTW, while you can; lightly sand the magnets in the flywheel and also
the magneto contacts. Just shine them up a bit. Nothing serious...

You don't want the parts to scrape.

What oren said.

But it's not a spark gap. There's a gap or space, and it's at the
magneto, and it is part of causing the spark, but the spark gap is at
the spark plug.

I agree with Al. I worked in a small engine shop many years ago and
one of the old timers had us use a business card to set the
clearance. It was pretty close to the correct gap and a lot easier to
use then a feeler gauge.
