I have a Robin but they all are pretty much the same for plug gap and tappets. I worked in a lawnmower small engine repair shop for many years in San Diego
I set them all the same and never had one return. I just did mine a couple of months ago and hand lapped the intake and exhaust valve seats. Starts first time everytime like the 7.5 year old unit is new!!!
Plug gap 0.19
Tappets
Intake .005 cold
Exhaust .006 cold.
