My carburator over loads up with gas. Worked great last year.

Started it up this year and carb loaded up with gas. Quadrajet carb

I took it off a just had it professionally rebuild because it was loading up with gas. I put carb back on started right up then loaded up with gas again.

Then I tried to restart and it seamed like it wasn't getting any gas.

After a few minutes I started it again and it loaded up with gas again.

Do any of you know what might clause something like that?

keep in mind a well respected carburator shop just rebuild carburator yesterday. so I don't think it could be the float

The needle and seat aren't seating. Cheap carb kits have bad needle and seats from my experience. Redo the carb with a Delco kit. Seen it to often.

The floats are sticking. Maye due to sludge or adj. If old then a maybe, but doubtful a rebuild is in order.

It will also happen when a fuel pump is putting out too much pressure. This happened to my 5.7L and had to make up some fuel lines and a Tee just to hook a gauge up to verify. The fuel pump quit entirely within the next season.
