No spark on left side of motor

The new shim will float on oil after you put it in. You will likely get too tight readings till you squeeze that oil out. I used to only go 1 size thinner before riding and checking if in doubt.

Cool.

A couple turns of the crank with a wrench after a shim change will squeeze out the oil under the shim.  I made many 2 shim size changes without a problem.
