Help! Cold start issue continued - attached video

Hello everyone,
After adjusting the set screws out an additional full turn, I still cannot get my GW to start from cold without a shot of starting fluid. I added this video which shows what happens (or doesn’t happen) from ice cold (70 deg), turning the key to ‘on’ pumping gas, cranking, attempting to pump more gas. PLEASE any feedback you have would be helpful! I’ve adjusted the choke as well, but I think there’s a problem getting gas in the carb.
Once I spray starting fluid, it fires right up, and will start afterwards (without the ether) with no problem.

Several things.

Your choke isn't closed all the way. choked means choked , though at 70 degrees it shouldn't need much.

Starting fluid can mask weak spark. if you're not getting 12v on start up starting fluid may be helping you out.


The most obvious thing to try is to pump the hell out of it, richen it up. make the accelerator pump give it gas so it doesn't need a choke. if that does it then you need more choke .

I agree on the choke, it should be closed 100% at cold start and then it should immediately open a bit once the engine starts. (This is done by the vacuum pull off, brass colored thing on the left in video)


I would start by opening the choke by hand and looking down the carb throat while you pump the accelerator by hand. You should see gas squirt out into the carb. If not, the accelerator pump is bad. I don't think yours is working.


Next, with the engine cold, close the choke 100% by hand and crank the engine. It should start almost immediately. Adjust your choke thermostat to close the choke when cold.

I have my choke wired open and with 3 pumps of the gas she fires right up even when it is down in the thirty's.

That being said I have the Ford TFI cap and Coil with a Accel HEI module DENSO 4708 Iridium TT spark plugs. Also running Single 0 battery cables with a group 24 Battery.

FYI here is the parts list for the Ignition upgrade:


Here are the parts I ordered from Rock Auto.

I used two spark plug wire sets to get fit I wanted with out making up wires.

You can get by without a choke as long as you don't mind sitting with your rig until it warms up a bit. but it's better to have it working.

choke not the issue

#1 check the carb has fuel in the bowls Hit the Accelerator pump see if its sprays fuel (Could have an issue with leaking the fuel out of the bowls when it sits or a weak pump)

#2 if the carb has fuel check spark see if its weak or if its getting 12 volts on cranking try jumping 12 volts to the coil (should have 12 volts cranking 6-8 in run position)

#3 tune up spark plugs wires cap rotor coil

I run a relay to power the coil giving full 12 volts, my starter barely turns over the engine before almost instantly it fires up.

Cold day staring she needs a minute or two of warm up.


I thought about converting to a manual choke, I even have the kit but have not seen the need to install it yet.

The choke absolutely matters unless you compensate by pumping the accelerator pump . one way or another a cold engine needs more fuel or it won't start it's as simple as that. his choke isn't closed and he's not pumping it so there isn't much reason to look beyond the obvious until he addresses one or the other.

while i think you have other issues as well,that choke should snap shut. fix it. that looks like a typical OTC reman carb,which is basically the same as a junk carb but cleaner. the choke unloader is out of adjustment too,i can see.


the accelerator pump appears to be bone dry or not giving a full shot either.



what set screws are you adjusting?



next time,hold the choke flap shut and see if it fires up.

It should start with the choke like it is. Look down carb and stab throttle. Does gas squirt out? I'd skip the starter fluid every time & pour 1-2oz gas in carb instead. Chokes not 100% necessary but makes life wayyy easier in winter.

Most engines at 70 degrees will want choke. Yours may not, but many will. Automatic chokes work awesome when adjusted properly and make you pull your hair out if they are not.

I love how everybody quiets down in silent respect one Ristow comments about a carburetor issue and nobody dares to argue against him.

I love how arguements end as soon as Ristow comments. Ristow is right...again.

Thanks guys for all the great information! And I LOVED the 60s era video, actually super informative! I’ll make some adjustments and check the accelerator pump...I think I’m not getting any gas at all on initial pump. Stay tuned!!
