Dave, if you want to use Autolites, the number is 216.

Wayne, Does the 430 use the Autolite 216 also?

Yes, I use them in the 40-420 and 430. They seem to not foul as bad for me. For example, the other day I started one of the 430's up and had the choke all the way out. It started right up, but noticed it was running rough. let it run a few minutes while doing something else and it still was running badly. For some reason I had forgot to put the choke off.(must be old age) Pushed it in and it ran perfect. Other plugs I have used would have fouled out under a circumstance like this.

Thanks, I looked in the manual and all it mentioned was the Champion number.

I run autolite #216 in all my upright 2cyl. and #388 in the rest that are styled.I used whatever I could find in the unstyled I think champion. I try not to use champion because I hear so much bad rap on them. But I have used some and can't notice a problem. I can buy autolite in a higher heat range cheaper around here.

I have a 420 and use Champion H-12 with 2 gaskets under it to raise the heat range. What Autolite would you recommend for a 420. With the champions I am getting a hickup/backfire through the carb.
