Oil pumping pony ???

Yes.

Dipstick usually jumps up and down too.

Might wanty to check the breather for blockage though.

Any chance the pony is overfull with gasoline diluted oil? Or just over filled with oil? I think they hold a quart. Could be the reason you are getting so much leakage.

Well worth a proper cleaning which includes drilling out the soft plugs and running a drill through the passageways. So many have fuel supply problems from the tank and lines being full of rust, but sounds like you have eliminated that. The carburetor is on the receiving end of that gunk as well as varnish problems from gas evaporating in the bowl.

The one that I found to be my problem was across the bottom of the bowl from the high speed needle to the plug that holds in the high speed metering well. I had blown it out with ether and compressed air, but the pony just didn't have any power. It would only run with a lot of choke and barely would start the main engine if you were careful. The last time I had it off, I finally bit the bullet and drilled it. After cleaning, I plugged the hole with a bead of soft solder I melted off some rosin core electrical solder. Just tapped it into the hole. Others have used a sealant covered BB shot or lead pellet.

Have fun!

By way of comparison, the high speed jet and passageway on my carb is good (although I haven't tested it under load) but the pony won't idle without choke, so I'm going back in to the idle passage which also runs along the bottom, and particularly the idle orifice which sits right in the bottom of the float chamber. I suspect when I get that re-cleaned ( I was sure I did it last time but...), it should idle nicely after that.

just a thought... Napa sells a one gallon container of carburetor cleaner, it even has a basket that u can put all the small jets of a carb in, EXTREMELY effective
