I acquired this today from a family friend. Fuel tank was pretty much straight varnish, I dribbled oil in the cylinder and cranked it over a couple times, if fires and runs for a couple seconds with gas down the plug hole, so it has life. He thinks it’s a 620? He said he bought it new in 1980

Here you go- you can work it out yourself.

Looks like a 621 from what I am seeing in pictures. I will look for the tag tomorrow when I go out there, thanks for the chart.

Thats what it looks like to me too- but no fun in saying its a 621.

The letter is cast into the case just below the top cover union and above the gas cap.

If it is I have another here somewhere. Both are complete, but I would rather revive this one.

Definately a 621........and a late model at that.......so if he said it was bought new in 1980 that would stand to reason.
Even still sporting the sparkplug cover....that in itself is rare.
