Lynn,
My plugs always have a rounded tip
after 15-20 hours. By then they are mis-firing at idle and I chuck
them. (Actually I have a large drawer full of them from the last 735
hours of operation!)
These are the factory NGK BUR7EQ and 9EQ
(cheap). If I were to try a colder plug, I am stumped on the listings
about what to try and which will fit without grinding off those ears on the
rotor housing.
Could you steer me to a part number that I could
try? No liability, I promise.

The higher the number on NGK plugs the colder the heat range.
Try the 10s in fine wire if you can find them. I use 11.5s to race
on.
But $25.00 each is a bit steep. I had some Champion N-57Gs and N-82s I was
using. The 82s are a bit hotter but caused no trouble. Any cross to the N-57G
heat range would work fine. NGK B10EGV Is the cross for the Champion and has the
gold Palladium fine wire tips.
Here is a nice site with crosses for heat range. I will find those
Autolight plugs and get you that number.
