Dead 6V battery, 12V jump start with pos and neg wrong

[Ed Northrop]

I would advise any one that buys a car with a 6 volt system is to buy a good 6 volt battery charger Sears sells a nice one that shuts off when the battery is charged and has a jump start option.

new car,,,, get a new battery

[Terry, NJ]

I have a 6/12 volt charger from Tractor supply and they're available at swap meets.

OK, with a new charger, a recharged battery and after screen & clean, the starter now turns the engine, I have a spark and there's fuel supply to the carb. However, still doesn't start.
I'm sure I'm doing something wrong with the start procedure. It's pretty cold here at the moment, about 35 degrees, so the procedure might be different from the one for warm weather.
Any hints what to set for spark, throttle lever, choke, mixture? How can I determine if I flooded the engine/carb?
Thanks for the patience :-)

take a look at this owners manual

Post #16 and 17. Have you tried them ?

The spark plugs should be dried out by now, but,,,,,, just in case.

Fuel can wash the walls and a squirt of oil can be a good thing.

While the sparklers are out, make sure you have good spark.

Thanks Mitch, I followed the procedure in the manual, but that didn't work.

I have the same problem some times when it's cold (fires right up when above 40 degrees no choke and no GAV adjustment). After experimenting a bit this works for me. Turn the GAV down and just crack it open and pull the choke out before you try to start it. Old plugs can also affect things if they're gas soaked or fouled and the cylinders will be wet as well from trying to start and they will take a while to dry out when its cold. If you have a new or dry spare set of plugs you may want to install them to see if it makes a difference.

Check to see if you turned on the fuel or has fuel and that you turned the key to the on position. I have forgotten to do this many times myself.

Somebody needs to come up with a set of jumpers that you could apply a 6 volt resister to nock down 12 v to 6v. For jump starts.

How Long has it sat? These model A valves will lock up fairly quickly. Add a little Marvels Mystery Oil (MMO) into the cylinders and let it set for a day or two.Try a compression test. Also, Get a can of starting fluid. If it fires on S.F., It's a gas/fuel problem. If it doesn't , It's a ignition problem. Starting fluid is excellent as a "drier" of wires, spark plugs, and distributors. Just spray it on and let it evaporate. Another thing to open the gas valve, under the tank, inside of the car, the handle must be pointing downward. It's closed when it's horizontal. Take the glass fuel bowl off and open the valve. If it runs out, it's clear, if not, you have a blockage, probably in the tank.

He stated he has fuel flow to the carb and has spark. I know your worried about flooding it but try extra choke, could be not enough fuel getting to the cylinders too. In cold weather I open the GAV 1 turn, hold the choke on for at least 3 revolutions, then when it starts turn the GAV to 1/2 turn open. When warm runs best at 1/4 turn open. If you have help, get someone to crank the engine and hold your hand over the air intake on the carb and you should get a wet hand. Tells you gas is getting through the carb.

Maybe check the Coil

[DirtyDuck]

OK, I'm a bit further down the road now. Checked coil, timed it.
It now starts with Starter Fluid/Brake Cleaner, but keeps running only if I continously spray S.F. in the air intake. As soon as I move the throttle without spraying, the engine dies.
Will try eagle's suggestion with the wet hand and then further track down the fuel system.

okay good diagnosis.... now you know fuel is not getting to the cylinders.. if you have a nice flow from the line at the carb then i would look into the carburetor....
its not flooded if it runs on spray..
you can also remove the fuel bowl plug under the carburetor to see if gas runs out letting you know the bowl has fuel... it's the bolt with the 1/2 head ,,, the other bolt next to it holds the carb halves together which is a 9/16 wrench size head... so dont touch that one

[Jacksonlll]

DD, if nothing happens when you push on the starter, put it in 3rd gear and rock the car to make sure the engine turns over and your starter is not jammed. If it is jammed, just push hard in reverse in 3rd gear. jack

Ladies and Gentlemen,

I have to deeply and sincerely apologize. I'm for sure the biggest idiot on the planet.
Found the issue: No gas.

I was tricked by the fuel gauge and the fact that the fuel filter cup was full. Also had some flow to the carb, but obviously that came just dripping out of the filter.

I have no words. I'm working on cars since 35 years, but taking apart half of the car and then figuring out it was an empty gas tank is simply embarrassing...

Now, with 8 gallons of gas, it starts and runs like new. Did a quick ride with my wife and then with my daughter. The truck is an eye catcher and it almost rides like a modern car (for me modern is everything from 1965 to 1985).

Thanks everyone for all the good hints and help and everything. At least my stupidity made me rebuild a starter, learn how to time the engine and get an understanding of the electrical and fuel system.

And now I go and get drunk.

[Mitch//pa]

you got it my man....
i was imopressed with your diagnosing to run it on spray, as we are not used to that here....

glad she runs good and as you stated
you learned alot..
this thread will help others in the future

Yeah! And the comment on Sear's 6v charger... ~$35.00 auto voltage sensing...

Thanks Mitch, the diagnosing is obviously something buried in my German genes
