engine flat head 6 6 volt system 1950 pontiac
new coil
new voltage regulator polarized as per instructions
points look good
new spark plugs
new wires
gas tank flushed of old gas, run about a gallon through the lines to flush
 gas at the new carb
battery fully charged

turns over fairly slow, shows spark at on tester but looks fairly weak


whats my next step as it is still not starting ????

Dont know if I want to do that, the fuel guage in the tank is really sensitive to burnout at 12 volts it turns over even had the starter spin out a few times , I think the old 6 volt systems were not speed demons on speed bill in red deer

Pull one of the plugs to confirm you have fuel. Or even try to flood the car to be sure fuel is in the engine. If you can't flood the engine your still not getting fuel for sure. Some times I've tried pouring some fuel down the carb to see if it will fire. If it does then stalls after a bit, your still not getting gas to the cylinders. There is a small pump in the Carter WCD carb, and it might not be working.

you can check here on the WCD Carter carb.

Now that I look at my Manual, I'm not sure if you have a WCD, or WGD carb. you will know by the vin tag screwed to the back edge of the carb. But both I belive have a pump for starting the car.

Rolilk..the carb specified fot the engine is a Carter WA-1 717S, I will keep trying to get it started tomorrow if it dont snow tonight, yes the S word is a possibility for us here in red deer will do more to check for gas in the engine , will keep you updated bill in red deer

Sorry on the model of carb..My mistake Looked again and saw this to be true. Hope it goes well for you this weekend. Snow oh well we all know this is comming.
here is the link to the WA-1 carb

if your scared on jumping it with a 12v boost why don't you try with another 6 volt to help give you alittle more juice. It works for me. I now keep an extra 6 in the garage for those times when she's a bit stubborn to start.

I used to jump my old 51 Chev with a 12volt battery, never had any problems

Well we did not get the snow but she was miserable out today, temp said we made it into the low didgits but with the wind a sprinkling rain it felt way colder,maybe tomorrow bill in red deer

Bill, try cranking it over with the s/plugs out, if it spins over OK, check your timming, you may have too much advance in it!!! Is it a "new " rebulid" might be a little tight???  Pete

pete, no its the orig engine, it turns over but fairly slow, this is probably the first time in 20+ years its been started. like I say I flushed the gas tank and lines to the carb, new carb on it, and all the other stuff as lasted avove I guess I will have to see if I can find a timing light, , I did not disturb the distibuter in any way uther rthan to check if the points were opening and closing , I basically only need it to drive off the trailer back into the garage she's heavy old car and its a fair slope int the garage so its a lot of hand winching bill in red deer

i know with my carb the float was not adjusted right (off by a fraction) and it was hard to start. I also had to fool around with the dist. to try and get it started when i first got it so if you have one of those ignition buttons that way you can try and start it and be looking at the engine at the same time and adjust whatever needs adjusting.

Can you post a video to show your slow cranking?

Also, the battery cable are very important (caliber). If you have old small 12volts cable style, with a weak starter, it will not spin very fast.

I use to have 6 volts, and I know it is not very fast on starter, but you will not spin enough with all above.

If you have correct cable, battery and starter,  you may be have to look at voltage leak into the starter system, and after if OK, look for the starter itself.

Fitz.

Do you have spark to the plugs? Clean the points with a fine sandpaper and reset them to make sure you are getting max spark. If the starter is dragging from sitting around you may want to take it apart and clean it up & maybe put in new brushes?

Starter.

great idea guy's, once I get it into the garage I will pull the starter and have it checked , might even have a spare that came with the other motor and see how that one is

Yup Timming might be a problem too? Was thinking of that.

 

I am wondering about the timing , assuming it run 20 years ago, I have not disturbed the distributer in any way, should it not still be close what would have changed bill in red deer

Might , but might not be. Its kinda hard to find out when its not running. You can check and see if your gaselector is set to "0" position, and try that.

Starter.

Agreed that is most likely the cause of slow spinning. Old starter, little corrosion or wear inside, brushes, armature, contacts ...

Also check cables, it is easy for corrosion to have gotten in there, not easy to see when all is hooked up, take them off, inspect the ends, clean the terminals with wire brush. Be sure to check the ground cables too (not sure on early cars but most years had something to go from negative battery terminal to engine block to frame and etcetera, all must be good).
