1940 Ford stumbles when making a sharp left or right turn

[mike42]

New carb has run very well the last couple months, but when now making left or right hand turns onto other streets.....it stumbles and acts like it's not getting enough fuel. Going straight on roads no probs. I've got the electric pump and a fuel reg. Could it be a sticky float ?

Thx.....Mike

water in the carb bowl--try draining the bowl using one of the plugs-drain into jar lid and look for water

While not disregarding the suggestion above (I wouldn't have thought of that) my first idea was low float level.

X2 on low float bowl level. Mart is smart.....

I'm with Mart... the cornering thing brings me to the same conclusion.

Guys thx.....It's a Dennis Carpenter Carb and I have a call into the guy there now.

Thx very-very much !!!!

Just as a follow up....I spoke to Joe's Antique Auto in Mass. area and he called Dennis Carpenter as it was their carb. No problems sending back and it'll be taken care of. I made it a point of including a copy of this web site responses with the Carb.

Great follow up with both part houses !

Thx again.....Mike

JMO, and my $ .02 worth. Box up your old carburetor you replaced with the new one, SEND IT TO CHARLIENY. Let him work his magic on it!!!



1.) You will have an "EXTRA" for times just like this. You will have an extra in case of ANY unforeseen emergency.


2) I promise you, once you install his carb.....you "MAY" have to make a slight adjustment on the air mixture screws AND "maybe" adjust the idle screw a touch......BUT That is it!!!!!


3) it's cheap insurance!!!


Glad to hear that the first one is getting taken care of with no real hassle's!!!

Check to see if your motor mounts are well tensioned or soft. If the engine moves under a hard pull or braking, an abraded wire making contact with a ground can produce that effect. It is rare, but we have seen it. So can a loose contact at the coil or distributor.

Rock and Supre....thx. Will look into it

Thx...Mike

Just a follow up.....Joe's Antique Parts and Dennis Carpenter were really great. They worked and worked to get the carb to work but no luck. They sent me a new one that I got in 3 days shipping and installed this week and runs great. I still intend on getting the original Carb rebuilt just to have on hand.

They could not find out what the problem was with the other one I bought from them !!

Thx.....Mike

Morning ….. I’m going to have the distributor rebuilt this Fall and was wondering if anyone has Charlie NY contact info as noted in this string of messages.

Thx…….Mike

Rock thx.....

It was recommended that I pull it out and have rebuilt by Charlie. I think you said that.

I'm just a little leery of pulling it out and then having a hassle to reinstall it !!

One thing that I did do that was recommended....it I had the "original" 1940 Coil rebuilt by Skip Haney and with the new carb it seems to be running very well now. I would pull the Distrib when I store the car for Winter and worry about re-installing in Spring or if I get some nice weather I'd do it before then.

Thx much for the info.

Either Charlie or Mike is very capable of doing your distributor. I personally have not sent a distributor to Charlie BUT I have sent numerous carburetors and fuel pumps. I have a couple of fuel pumps I NEED to get to him right now. Mike at Third Gen has done several of my distributors (he's much closer to me location wise). PM me your address and I will send you a set of my home made distributor studs that are a tremendous help for installing your distributor and making sure the offset key way is lined up correctly before you install the bolt into the block!!!! They also help hold it in place so YOU don't have to sit and hold it while trying to line the key way up!!!! OR you can email at [email protected] and I can send you pictures of what i made and you can make yourself a set. They are a God send!!!!

[mike42]

Rock....

I'll send you an email.

I spoke too soon.....installed the rebuilt coil and she fired right up and idles perfect around 300 rpm. It still stumbles now until I get into 3rd gear. This is crazy as hell. The only thing I haven't changed is the electric pump and rework the distributor. If it was the Dist you'd think it would stumble all the time !!! That wouldn't be intermittent I would think. This has happened to 3 carbs now !! You'd think one out of three would work !

Check the vacuum brake nut on the distributor and the whole vacuum advance line for tight fits and or possible leak. Eliminate that as a possible issue

ALSO Not sure what "stumbling" means BUT what carburetor are you running??? AND Have you tried relocating the accelerator pump rod position on the throttle linkage???

Mike
Do you still have the original wiring?
Check for a bare wire maybe thru the firewall.

Rock....I'll look into changing it. Stumbling in my terms means....when you press on the gas pedal....it acts like it's not getting enough gas and the engine bucks. When I get through 1st and 2nd gear it smooths out. It starts on first turn of the engine and idles perfect at 300 rpm's. The car has run perfect for almost 10 years. I've gone through 3 carbs and I can't believe all 3 are bad !! I'm in the process of by-passing the fuel Regulator and going straight from the electric pump to the carb this morning. We'll see !!

cmbru.....car was rewired about 20 years ago I would say. I've checked that, but who knows I may have missed something.

More later....I either need more coffee or a Jack Daniel's !!

Not to beat a dead horse here, but thought I would chime in on the stumbling issue I was having. Somewhere online I found an article regarding Holley Regulators. There has been problem with the 803 and 804 units.803 is for much higher pressure and the 804 is for 1 to 4 psi. Apparently....in China that place we love.....one spring is marked with a red streak and the other is not marked at all. Some 803 springs were put in the 804 units causing the type of problems I was incurring. So.....I had an old 804 unit and took it apart....sure as hell it had a red stripe on the spring. I then opened up the "new" 804 unit and NO red marks on the spring and it was a higher in size than the one with a red stripe. I took the red marked spring and installed in the new 804 unit and bingo.....started right up....held constant pressure to just under 3 psi and no stumbling at all ! Back to idling at around 200 to 300 rpm and it's back to running smooth again. Just went for a 15 mile run and no problems.

So in closing....."new" doesn't necessarily mean it's good !!

I've got another 804 coming just for a back up and for sure will check that damn spring !!

I can't believe I went through everything I did and this is the root cause of problems.

I appreciate all the info and help ! Trust all are having a great Holiday weekend.

Thx.....Mike

Thanks for reporting back! Seems the regulator had more spring pressure than the pump could overcome . . . so you were fuel starved.

3 PSI is fine for Holley or Ford 94 type carbs, but a bit much for Strombergs. Glad you sorted it out.

[mike42]

Bored………I am too, but who would ever think that there would be a mistake when assembling a spring !!

Thx !
