Whining about my carb problem

[DeltaMustang65]

Sounds like a plan. I'll probably be able to get to the carb tomorrow morning, but I can look around for the procedure tonight. Mustangs Plus seems to only carry the same linkage that I already have, from what I can tell.

I DID get their export brace and monte carlo bar in the interest of stiffening up the engine bay for when I upgrade the suspension (got some questions in "corner carvers"), so I've got a busy day ahead of me tomorrow. It's been awhile since I've wrenched on this car, so as you can imagine, I'm a little excited.

After installing my other junk, turns out I wasn't excited enough to get started on the carb. I'll get to it soon though.

I didn't find the actual float adjustment procedure on MW last night, but I'll look again. I think I should have the procedure in my holley modifying book at home, but I'm not there right now so I can't check.

Anyway, just thought I'd let ya know that this is gonna be on hold for a day or two.

Well, looks like my carb book "super tuning & modifying holley carburetors" has the float adjust procedure in it. Looks very simple, too. I'll give it a shot tomorrow if I get the time, and let you know how it goes and if I need to adjust anything else.

Ok. After class today, I'm going to head back home and adjust the float and see if that helps. In the interest of trying to get ahead of the game, what else should I be looking at on the carb once that's done?

Well, that was fun. Seems the carb was pre-adjusted to where it was dripping 2-3 drops of gas per second, so I adjusted it so that it dripped once every 2 seconds. It helped, the little lag is all but gone now, and even then I might be confusing it with the secondaries opening. Do you think that the carb was getting a little too much gas for it's own good?

Thanks for the suggestion, Ryan. I'm not quite so intimidated by carburetors anymore.

Where do you suggest I go from here?

Are you talking about dripping gas into the bores at idle? There should not be any dripping at all. Only at higher rpms should you be able to see gas flowing from the ventouri boosters into the carb bore. I'm wondering if the needle and seat is leaking? That will certainly make gas drip into the bore at idle creating a rough idle and black smoke from being too rich.

Adjust the floats so that the gas level is right at the bottom of the plug or if you have a sight glass right in the middle of the sight glass. At idle the only gas getting into the bores should be from the idle circuit which is not visible.

Oh, crap! I'm sorry Rev. I got disconnected the first time I was typing that up, so the 2nd time I was too hasty. I meant that I adjusted the floats so that the gas was barely creeping out of the plugs in the side at about a drop per 2-3 seconds. This is what I'm going for, correct?

If I'm good, what should I be looking at next?
