Yep. Used to be (I'm old) that the AFB only had 3 nozzles. The small was really small. The medium was what fit most stuff. And the big nozzle was big...IIRC up around .045 and that's what most tunnel ram stuff took for those carbs.
I'm thinking its going to take a pretty big nozzle and the longest shot you can give it. Sometimes you need a bit smaller nozzle to make the pump shot last longer.
Big nozzle=huge short shot of fuel.
Small nozzle=smaller fuel volume for a longer time.
Sometimes you end up with the same volume with different nozzles but the length of time of the shot cleans up a bog.
Just as a hypothetical, let's say you have a 28 nozzle and with the full stroke it's 10cc's of fuel. And just for fun we will say that shot lasts three seconds.
Now you go up to a say...45 nozzle with the same pump stroke. You may still get 10cc's of fuel, but it may all get there in one second.
My point? Sometimes it's as much about the timing of the shot as the volume.
