Default Spark Plug options for early PANs

Just curious what you guys are running for plugs in your pans?
Ive read difference of opinion in regard to range in gap (.020-.032) and brand.

My motor is a 1950 74" pretty stock except a SS Super E.

I just want to add that with today's lack of quality control you cannot assume that that new spark plug you put in is actually working.
We had a so many guys going nuts trying to find out what's wrong with their bikes after doing a tune up when the only culprit was that brand new faulty spark plug.

I bought 4 plugs several months ago Mike, all 4 WERE DUFF. I spent a good few hours faffing with my bike to test them all and all were dead. Awful to think the QC like you mentioned is abysmal.

I even take one off one of my cars if needed to check that to make sure it is the plugs not the electrics.

Years back I mounted a car coil, points, and condenser on a piece of plate. With 2 leads with alligator clamps to connect to the battery of the bike or vehicle and a spring clamp to hold the plug for testing. Doesn't prove plug will work under compression, but does show if it will arc.

Curtis,
I've also had good results with the Autolite 4275. They are cheap and reliable; I buy them when they are on sale here locally for less than $2 bucks each, They work real good for a kicker and points bike like our old Panheads.

odd isn't it , when I was v' green to bikes I thought that it was the plugs that were the prob' with a poor starting issue and have steered clear of Champions ever since, anyhoos my lack of patronage doesn't seem to have done them any harm and indeed they are the first choice of regarded competition riders. however a 0.19 gap seems kind of big with a mag', would expect mebe 0.14; what's anyone else got to say?.

59,

When I first put my mag on, It was playing me up a little but I put some starter fluid down the pots and got her running sweet, When I came to check my plug gap it was 0.26 and 0.27, I took the bike for a spin and it ran sweet as a nut. I set them to 0.19 as between 0.18 and 0.20 are recommended. Bike pulls like a train compared to prior to the mag. Infact I had 103 MPH out of her today on my "private road".

I have run bunch of different ones now.

Autolites always work the best.

I am running the XS fine wire type in there for the past 3 years no issue. Runs better than the 4275 in my opinion.
