Default carb trouble

Hi. I recently had my 65 289 mustang sitting for a period of about 3 months, Started out when my brakes went out, and because of the stock booster it took me some time to figure out how to make parts to connect a dual master cylinder off of a 67. Finally got that figured out and now it wont idle properly. I took it for a test drive with the new brakes, and it worked fine (well the brakes were a little slack, but fixed after i rebled them). I noticed that there was some gas leaking from the carburetor onto the the intake manifold, saw a bad gasket, and replaced it. Now when i try starting it, it sounds like its running well when i give it gas, but if i try to let it idle it dies. Hoping it was just the idleing arm, i adjusted that, but no luck, runs, but idles out. The Carburetor on it is the stock 4100, and i noticed that the automatic choke was disconnected on it. Is it possible theres some damage to it? I notice it seems to be burning to rich a mixture and id like to not catch my mustang on fire. Any suggestions?

Sounds like you have a vacuum leak. Since you were doing brake work, check the vacuum hose to the booster.

i would suggest vacuum leak as well. if you have a big leak it wont idle and if you have the curb idle set so that ther engine will idle (high) then you can see a bit of petrol spilling from the boosters. telltale signs. plug everything at manifold and carb and see how that goes

thx :-) they are Cragar Quick Trick I
they are cheap, but they are steel, not alloy (very heavy), they rust very very easy and constant so I have to clean them all the time. really annoying. PITA wheels, but look good. Still I'll replace them with alloys at some stage as I can't do the cleaning up anymore.

i know its been forever, but i skipped town for a bit. I ended up rebuilding the carburetor and found out that the problem was that i had accidentally moved the idle screw when i was replacing the gasket. problem solved haha. Well now i know how a carburetor works :P
