Default Will only start by putting gas in the plugs

Searched forums and did not find anything. I am trying to start my car after it has setup for a couple of years. I installed a new carb"zenith 2" just before I put it up. I did not crank it though. It has fresh gas, sparking.i tried cranking for a few secs and flooded it . I put some gas in the vacuum hole on the intake and it fired up and run great. Adjusted carb and went to sleep. Tried to crank it today and nothing. There is plenty of pull through the vacuum hole.(I do plug it before I run it).any thoughts? Why would it not pull the gas up without priming it?

When you got it running, how long did it run? Did you drive it? Does it idle OK with the spark retarded? Did you have your GAV open 1/2 turn when trying to start it?

Sounds to me like you may have a blocked passage or passages in the carb. Since you were able to inject fuel into the intake, you didnt flood the engine just the carb, which means you should be getting some fuel flow to the carb. I say pull the carb and look inside, may need cleaned.

Did not drive it ( seat will be ready tomorrow).ran it for about 20 mins, new radiator in it so breaking it in. Sorry what does GAV stand for? I know I will slap my forehead when you tell me. It dies when I advance the spark all the way. Could not get the carb adjusted right for that.

i think your best bet would be is to find a model A club in your area for some help on setting things up

That is a big problem. All my experts are dead. Howard green(master builder) Curtis Clark ( master of all) and my dad. The ford restorers club of ms is long gone and all my numbers for past members r wrong. I have driven this car for 30 years without one problem with A model experts just houses down from me. Anyone know someone in central ms? Lol

Huff , I noticed my choke was not fully closed. I need to look into that when I get off work.

You mentioned you installed a "new" carb. Do you have the old one still and could you put it back on to see how it works? The GAV is the gas adjustment you make turning the choke rod.

How clean is your gas tank? You said you let the car set for a couple of years. Could there be stuff in your tank that stops the flow of gas?

I had this one rebuilt. Once this one starts it will run fine and start on its own even after a hour. I do have new one I got off eBay . I might try it.

So it does run OK for a period of time. Maybe your idea of checking the choke to see if it is closing enough to start may be a good thing to check. One other thing you could do if the choke is not working, have someone put their hand over the end of the carb where the choke is while you try to start it.

How is the gas flow at the fuel line at the carb when opened?
It should flow STRONGLY.
How about when you open the drain plug under the carb?
Does gas come out?
Do it again in a minute and see if the carb filled up.

Gas Adjusting Valve. It's controlled by turning your choke rod clockwise or counterclockwise.

Did you open the gas valve on the tank? I forget to do this every once in a while. Mrs Sturgis says there are more pedals than she has feet and to many other things to remember like the spark lever, the gas valve, the starter button on the floor, and the GAV and the choke. I get a kick out of her verbiage when I ask her to drive the Model"A" so I can see it in motion. She thinks that this is real stupid too. I can hardly keep from smiling while she is scolding me.

She drives the 39 Ford. She thinks the pedals are too high and she feels like she is a dog trying to scratch his ear.

I have not driven this car in a couple of years but learned to drive it when I was 8, so you would think It is like riding a bike. but without a front seat and setting on the floor board( I am 6'5 so I could drive like this) I did have a little trouble doing my routine starting it. I am at work for 24 hours so when I get off in the morning will check gas flow from the bottom of the carb and check back in. GAV ( slaps himself on the forhead!)

Assuming your points and timing are set correctly, that is a symptom of a short inside the distributor. The lower plate wire or tab may be grounding against the distributor body. Try driving it without advancing the spark lever to the point that it dies out. Does it still stall out?

Quick Answer: changed Carbs and works fine.

long answer: the reason why the first Carb had issues, When I got my carb back from the rebuilder I used the liquid seal from Mike's on the fuel line going into the carb. When I checked timing and spark and gas flow it had to be a carb issue so I put my spare one on. when I took the gas line off I found some of the dried seal in the gas line and sticking thourgh where the gas goes. I am guessing at this point that some of it got through and has one of my jets stomped up. will take it apart and see. I thought since the car would crank on its own after putting gas in the plung that the carb was working right. Never assume anything.

thank you everyone that posted, I am learning alot from this site.

BTW it is the 50 year aniversary for the Amodel club of Mississippi. I found the members and rejoined the club.
