Hi,

I saw a 420c with the rubber blocks on the pads doing a tractor pull. Off one of the recent Yoo Toob links, I think. So, for a crawler I think those are slicks!

Lavoy is right again! Turns out the 40C was burned and rewired by my electrical engineer brother while I was away in the Army. He added the resistor to save the points, but when I changed the coil it had to go. And he used all red wire.

Hi,

Ah ha! All red wire is fine, if you use Brady wire marking tags on them all to figure out which go where....

As far as electrical engineering goes, they skipped Ignition Systems 101 when I was learning it. I got my schooling in that field way earlier.

Me too. -- "Hold that plug near the hole while I crank the engine over. Let's see if there's any spark"; no rag, no glove, no joy.

Paul-- There might be a little humor in the plug holding, if you're not the holder.
