I was cleaning out some drawers in the garage today and came across a Champion C59CX recessed plug I tried to run one weekend at the river many moons ago. Killer super duty race plugs the damn things fouled going up river. They kind of glazed over.
We had run them on the dyno in either '98 or 2000 and the worked just fine. I get to the river and I'm headed up river and the boat starts getting lazy as if the timing is retarding and it finally just quites in the middle of the river. WTF we had gone 3-4 miles. I pull out the nasa tool box we carry and start looking for the cause and 4 of the plugs look weird so I change them out to the Autolite 51's I had in the boat. This took abit to get to the plugs being the issue after checkin fuel the dizzy and maybe something else.
We take off and about 1/2 mile later the it losses power again I check the other 4 plugs and damn they're glazed over too. I throw in 4 more Autolites and away we went. Those damn Champions just didn't like something we were doing, 3,800 rpm cruise or the fuel. /they just checked out. So I've run the Autolite 51's ever since.
I was a bit surprised that the MSD and the hot coil wasn't enough to keep them firing.
