MSD & ignition plugs + plugs gap...

-
I've been running MSD stuff for 20 or so years and never had a failure. Heck, I even ran the 6A on my little (60 ci) International tractor. :D
 
And if I did ever have even three failures I would be done with MSD forever. It sure as heck wouldn’t take me 10 failures to wise up.
