What spark plugs in an Allis WD?

[Will Herring]

Figuring it is a good time to acquire some parts for a tune up, and curious what spark plugs people are buying these days for their WDs.

Also, who do you guys go to for good quality new plug wires, distributor caps, points/condensors, etc. these days.

Oh scratch that question, I see the parts are all available here under electrical (I was looking under engine, whoops).

Maybe unlike yours, my gas tractors don't ever work hard. I put in the hottest plugs I can find.

I'm pretty sure it takes the same plug as the WD45 and I use NGK3112 plugs in my WD45

Thanks Bob & old. Appreciate the feedback!

My WD45 would foul out the plugs till I put in the NGK plugs and it has not fouled them yet an that was a couple years ago

AC Delco

AC Delco will not last one day in my WD45 before there fouled out but the NGK have been in it for a couple of years and still going

I believe it was AC Delco R43S I put in a CA that had a oil problem on one cylinder and it wouldn't foul, just burned the oil with it.
