engine is L-head 4.5hp
ok what I've done so far:
checked spark, cleaned carb, flywheel key, all checked ok.
took compression check 60psi.
pulled head off rotated flywheel and noticed that at about 3/4 up on compression stroke the exhaust valve will open slightly then closes.
(this is new to me) thinking maybe cam lobe may have been ground wrong.
or is this something they came up with to lower compression for some reason?
