That Z in that plug means it is an inductive resistive plug. It’ll have to have this plug in order to run without a miss. Do not run champions in that motor, and do not run autolite plugs either. Neither will work in this application.
Its designed to run those plugs to suppress RF interference.
Running that application with the wrong plug could potentially damage the switchbox
Thank you! I'm just going to order a health supply of them and put them up.
You will still have to order some next time you need to change them or spend all day looking for where you put your extras. I know because I had to run to the store yesterday in the middle of cutting grass to get a 20 amp fuse i had blown when I know I have at least 2 boxes of them around here somewhere, just didn't have all day to look for them.
