Ive had in the past on my car, stromberg 97, float set perfectly to spec..
Lean of the engine in the car about 3° if I remember correctly. Gas will flow out the body of the carb where the emulsion tube enters the venturi. Trickles down into the intake manifold. Makes it tougher to start in a short time later.
If your parked on a slant with the front of the car higher than the rear it's worse yet.
I solved it setting the float level lower. In theory the spec. shows the gas in the carb. to be level. With the 3° slant its NOT.
So, I set the float lower, took it for a drive under different loads to see if it starved for gas. It never did.

Something to consider once you know all your electrical, fuel pump and lines, carb. are "known" good working order.
