Drifter,
Just looked at my Gale service manual. It covers from 1948 to 1963. Yours should be a 5D20B model. Not up to speed in this manual but found your 5D20 powerhead. Don’t know what the “B” means yet. Give me a shout at Jeff.50@cox.net & I can scan your carb breakdown or sell you the book. My health is bad & will never use it.
