1981 C70 carb issue...any Honda passport gurus here?

Meshuggah
My c70 Passport revs quite high when I start it and then dies immediately when given gas...I can adjust the choke to the point where it isles down a little...adjusting the fuel ratio screw doesn’t really seem to do anything. Before I opened up the carb it ran Ok just had a bit of a high idle.., now it doesn’t even run. Dies the second I give it gas.

Thoughts? I feel like air is getting in somehow, but upon visual inspection, the rubber tube from the carb to the air filter and air box look ok, although I haven’t fully disassembled them. Could it be the old seals on the carb itself? I definitely thought it was the float, which was filled with fluid, so I replaced it. But that didn’t do anything it still has this issue

You have a vacuum leak. Check the seals on the manifold between the carb and head. You can spray carb cleaner/WD-40 on it while it is running, and the RPM will change whan it hits the vacuum leak.
