I have a question concerning the Holley NH. When you close the choke and crank the engine (hand crank for me), is it normal for it to spit gas out the vent hole near the choke plate that faces the engine?
Here is a pic I swiped from the forum and I circle the passage in red. It leads directly to the fuel bowl.
Yep. Normal. And mine does it on about the second pull, which is why I always cringe when I see people suggesting to a newbie to choke for 4 and sometimes even more pulls. Mine would be flooded bigger'n crap!
Mine would be too Hal. Two pulls are the norm, maybe three pulls of the choke if it is colder (30 ish degrees).
I was just wondering about the gas spitting out though, it keeps that part of the block REALLY clean, LOL. I don't know what you fellas do with nice cars, but trying to keep paint on the block or the carb for that matter seems impossible with raw gas splashing on everything when choking to start.
I agree with Hal. It may also help to open the needle a quarter. The spit is normal
That looks normal to me. Every car is different, and each carburetor and ignition system is a little different. If it were mine, I would first try to start it without choking it. If it doesn't start, choke for one pull and then try again. If not yet try two pulls and try keep doing this until you learn just how much to choke the car. Wait a while between tries, so that the excess gas will evaporate between tries. Once you find out how much choking your engine takes, then do it that way every time.
