Angry At my wits end

Okay, this car is getting me impatient. After causing me to miss Sevenstock, it STILL will not RUN for the life of it.

Yesterday, the carb wasn't quite getting gas.

It would feed gas TO the carburetor, but wouldn't get to the bowels. It got lost in the horn tubes. I tried tightening, I tried loosening.

Today, I tried loosening them just a LITTLE bit, and now it's getting gas again. Apparantly too MUCH gas. I POURS out of every oriface, and looks to be a healthy amount. I try starting the car, and nothing. It started better when I had a gas leak on the carb (fixed that)

I turn the key, and the engine tries turning at the rate it turned the other day when I drove it a good ways (17 miles) home from where it was parked.

I've tried putting the throttle all the way down, I've tried different levels of choking it.

It has ALL fluids, a half a tank of gas, and still no start. Before, if I poured the gas directly into the carb, it would start. I don't think that's working anymore!

I really am getting frustrated with this car, and am wondering if ANYONE can help me.

BTW, thanks to those people that already have helped me out so much. I went from a car that wouldn't do anything (like right now) to a smoke mobile, to a rough running car that got me from Las Cruces, NM (east side of the state) to Yuma Arizona with minimal trouble, thanks to you guys.

Thanks in advance.

Was wondering what happened to you man. Pop the banjo bolts off and clean or chuck the brass screens. Whats the overall condition of the carb? Has it been rebuilt/cleaned ever?

Man, I missed you at sevenstock. Sorry you couldn't be there.

Where is the gas pouring out? Is it puddled in the venturis?

I popped the screens off yesterday. I'm thinking that's what's letting the gas through now.

I don't think it's actually flooding, per say. It's just getting gas to the correct level.

It's coming out of the little tubes in the little holes. I have no clue about terminology. You know, the big holes on the top of the carburetor that you look down on, and there's little tubes on the sides of the holes.

Also, the little triangle area BY those holes FLOWS out with gas. I mean FLOWS. So much it spills into the big holes (I call them bowels, though I'm probably wrong)

It's a fresh rebuild, by a forum member who shall remain nameless until this issue is solved (don't wanna ruin someone's name, you know?)

Ok. I think I got the picture. From what you're describing, it sounds like flooding. Fuel should not be running from that little triangle area. Under the fuel inlet, there's a brass nut thing that's the float bowl vent solenoid. it has an electrical connector. Is the connector hooked up? There should be 2 fuel lines connected to the inlets. Are both hooked up? One supplies fuel to the carb; one returns fuel to the tank. You need both connected unless you're running with a fuel pressure regulator and I don't think you are.

When the car is sitting in a level spot, what are the float bowl levels? You can check the levels by looking in the bowl sights - little windows at the front and rear of the carb. The level should be 1/2 way up the window.

Slashdawg's got it on the money. One thing you can also try is with the key in the ign on position, connect and disconnect the vent solenoid. You should hear it click. Thatll tell you that it is indeed working.

Thanks for the tip on disconnecting and connecting it. I'll try that now.

It is indeed connected. It seems that the float bowels are either full or empty?

So you can't see fuel in the sight windows for the float bowls? If you've got fuel running out, I don't think they're empty. Find out if the rebuilder adjusted the float bowl levels and if he replaced the needle valves and seats. I'd be willing to bet that the floats aren't causing the needles to close and you're just pouring gas into the bowls until they overflow.

Did the guy you bought the carb from rebuild it? If so, call him. If not, just take the air horn of the carb. That's the top part of the carb, held on by 7 - 8 screws IIRC. You have a manual, right? Or you can download one from a link in the FAQ. Get the '85 rather than the '80 one. And you can just download the fuel system part. Look at the page that shows how to check the float measurements and adjust. Helps a lot if you have calipers for measuring, but you can do it without them.

While you're at it, look at the manual and check that the needle valves and assembly are properly in place.
