Carb is basically brand new. I had it on my truck for maybe an hour of run time and went back to a 750. We had to use an adapter to put the Holley on the old AFB intake. We suspected/found a vacuum leak at one point and fixed it but no significant change in regards to the timing.

Floats are set correctly, trickles out the sight plug when you undo the sight plug. We actually raised them at one point, the fuel would slosh going around a corner and momentarily stall. Raised the float and it was fine. Didn't touch the secondary side.

Forgot to mention, there is a BAD valve tick on the pass. side, not sure which cylinder but it's loud and always present. Definitely mechanical, not an exhaust leak. We had a vacuum gauge on it and it was pretty steady. Has about 13" at idle.
