Do you have fresh, clean gasoline in the tank?

I thought so. But, most of it is probably around a couple months old.
That's an awful lot of goo for just several starts? When I did the valve job a few weeks ago, had just a bit of that in each intake from around 15 years of build up. Perhaps the intake manifold had a large build up that I missed and now started to melt from the several starts? Maybe need to boil out the intake manifold? It does look a bit shiny when looking down from the carburetor mount.

It's not normal. Stale gas can cause that. I've seen deposits of what looked like molasses form in the intake of a new lawn mower engine that only ran about ten minutes before the intake valve stuck open. Stale gasoline caused it. The goo was hard to remove, too. Your exhaust ports don't look too bad. I would wash out the intake manifold and try to clean out the intake ports and valve stem area. Then I'd drain all the gas out of the tank and lines and carburetor. Check that the crankcase oil looks and feels normal and doesn't smell like stale gas.

Had a couple garage owner friends to look at the oooze. They did not think it gasoline? I may remember years ago I had the gas tank boiled out with some minor repair. The shop asked me if I wanted to use an internal sealer, I told them no. I had heard of some issues in years past. But, I think they might have coated it anyway? Might this be from the interior coating coming undone?
I emptied some gas out of the tank, it definitely is a golden brown pale color indicating the gas is no good. Not in the tank very long, so thinking the sealer is the issue? I can drop the tank, not too difficult, try to have it boiled out again, but if I need a new tank? Where to get? One friend suggested MoPar Pro. Anyone have used them? Thanks Todd

The filler neck was a good fit? On the 1808 there is literally around half an inch clearance on a couple sides, from the frame and suspension. Thank you.
