Mallory Double Life distributor on a flathead

I've been using a vintage Mallory on my 8BA flathead and It's always run lousy.
It's a completely rebuilt engine and distributor and I've always had the points gap set at .020 like it says on the tag on the dizzy.

So today I decided to play around with it and I set the gap at .015, now it runs damn good!

Has anyone had a similar problem with these?

The advice on the tag is just to set it "static"....you should always run them on a distributor machine to properly set the dwell. Glad it's running better for you!!!!

 

Wish I knew someone with a distributor machine!

 

GMC BUBBA here on the H.A.M.B. is the dam best with a dizzy machine and has great hot sauce! He can dial it in like a champ. Look him up.
