Edelbrock 1407

Removed carb to put an insulator clean carb and check transition slot exposure. Couple of questions before putting it back together, any pros or cons to going higher or lower with float height dimension from stock 7/16” ? And also I’ve read that Herb Mc Candless at a seminar suggested leaving the weight out above the ball in squirter, makes sense to me, has anyone tried it with positive results?

I have never pulled the brass weight.
What problems are you having ?
Have you put vacuum gauge on and tuned it ? Springs , rods ect.

Only issue I have is a very small hesitation right off idle when very slowly easing into the throttle, if I step into it more no hesitation.
I have used vacuum gauge, changed springs, changed pump hole position, advanced initial timing etc. One of the reasons for removing carb was to take a look at transfer slots which appeared to be more exposed than ideal.

Have you checked fuel pressure ?
Also just to toss this in....
Sometimes carbs get blamed for ignition advance springs and weights problems.
I know something like a little stumble will drive you nuts when all else is working.

Get the orange accelerator pump if you're using the blue one. Todays gas will ruin the blue one. It's one of the main causes of hesitation off idle.

What engine size, cam specs, timing at idle?

I would NOT change float height. For reasons known only to Edel, they went lower than the original AFB. Only reason I can think of is that less likely of misfire from cornering/sudden stop where fuel could slosh into the t/bores. Going to a smaller float setting [ raising the fuel level ] increases this possibility.

Just about the only modification I've had to do on any of these is to bend the accelerator pump arm to increase the shot.
...and that is after putting it in the max shot hole.
Every one I've tuned on every engine (even stock 318) has needed this to get rid of the slight, off idle hesitation.
