Anyone know the fuel ratio for a Chrysler 20 hp, Think it must be a 70s model no (serial No )or identifiable marks.

You should be ok with 50 -1. I think I've got a manual somewhere so I'll check when I find it. Don't forget to change the gearbox oil (fill from the bottom) and fit a new pump impeller before using. Run in a tank to check operations. Heat any corroded stainless to ally screws or fittings with blow lamp to prevent shearing them. Use plenty of WD40 and grease.

We had a Crescent 20 hp in the 70's and that ran on 50:1, so agree with stanleyman that you should be all right with that.
