Starting fluid is a good way to get your ether.



I've seen some carbon fouled plugs that no longer worked correctly. We tried hosing them with cleaners, and hitting them with the wire wheel. The spark prefers to go down and then back up instead of jumping the gap correctly. The plugs were BUR7EQ (and I think it had 9s too) on a stock FB ignition with a dellorto and old tired oil seals (lots of smoke!). It's obvious to me now why it didn't work that well, but back then, it was a mystery. We put some new plugs in it and that solved the problem, although I don't remember which type of plugs there were. I'm sure the problem is coming back, or it will some day.



Basically, 2nd gen plugs on a 1st gen ignition system isn't a very good idea. It's ok with direct fire though.

 

usually a wire brush and some carb spray work great, but its like a 75% of the time deal, sometimes it judt doesnt work

THAT'S THE STUFF!!! I gotta get some! WOOO!



(no need for that stuff for the diesel though )

 

I think the reason for that is coming true. I put 2nd gen plugs as my regular NGK's were starting to foul, they made a bit of a difference at first, but they died off quicker than the old ones did.
