Well.... I have to hold off on that friend of mine Jack Daniels ! Started it up and it ran great...headed out on our side road here and after about 3 or 4 minutes it started to sputter and spit again. You could smell the heavy oder of gas ! No leakage this time, as I used new gaskets. So.....I put in the new fuel regulator and it made no difference. I had it set at 2.5 psi. I'm going to wait until new carb shows up next week and hit it again and see what happens.

You know.....I think I may meet Jack in a few minutes anyhow.

Fordy..... I'll for sure look up what you sent.

Hope you guys had a good weekend.

Thx all....Mike

Mike, Since I have a 1953 Ford V8 in my 40 I used the the Gross jet for the carb that was on that engine. I think it was a Holley 94. I don't know what Gross Jet would fit the stock 40 carb but, I bet the vendor could tell you and match it. I know the Holley had # 51 jets.
I would think that the vendor would need to know the manufacturer and model number of your carb to provide correct part. I bet these folks could help too. Peruse this:

Read the post in the link below by ford38v8. It tells info. about your carb.

Mike: I just found my 1986 receipt for my Grose Jet that I
bought for my Holley. A 3 page listing of all the Gross Jets and what carbs they fit also came with the part.

The list shows that Ford 94 v8 and 6 cyl carbs have a .084 orifice with 5/16-24 threads The Grose Jet Part Number needed is HY-32. I THINK THAT IS WHAT YOU NEED.

To be sure, post your carburetor, make and model number along with any other numbers you find on your carb and I will look thru the list for you and let you know.

Also, here's the website info. for D and G Valve Manufacturing Co., in Stoneham, MA that makes the Grose Jet item you need along with their phone number. I am sure they will know the correct Grose jet for your carb.
Give them a call to be double sure it's HY-32. I paid $4.50 plus shipping in 1986.

Hasn't this been an issue for power valves for 94s for years. Old archives are not available. The new ones don't seat without some milling. CharlieNY question and solution. Reason I like strom 97s

Fordy thx I’ll check it out and let you know.

Tinker ……I ran across another Barn member who had this very same problem. His name is Ralph S in South Carolina. Sent him a PM and hoping he responds to see if he resolved his issue. Thx for the advice.

New carb gets here tomorrow !

Mike, Just for the heck of it check the seating of your new power valve by marking the surface with a black marker to see how it fits surface on surface. Blue layout dye also works the best. Also visually examine the machined edge of the valve.

Fordy....this is crazy as hell ! I replaced the pump with a new one and also new needle valve and seat. Changed the power valve with a new one I got in the rebuild kit.

It fired right up.....ran perfect for 10 minutes and no probs. Came back in 20 minutes to take for a short ride. WILL NOT START UP AGAIN !! The regulator shows 2.5 psi and I drained the glycerin from the gauge also.

New carb is to be here tomorrow. I'll be working on it again, but in the meantime I'll check out the power valve as you suggested.

More drama, but it's not my brakes anymore ! They are solid !

Thx.....Mike

Did you check for spark when it would not start?

Flat...yes it has spark. It fires but, I'm getting a heavy gas smell. It's strange....after I've taken the carb apart and it's dried out and I'm changing jets and pump and power valves, etc.....it starts right up and runs sweet ! After I turn it off and go back to take a ride.....it will not start except like it's flooded !

Years ago....I had Skip Haney redo 2 coils.....after I get the new carb tomorrow or Wednesday....if I still have the same prob I'm going to change the coil for the spare I had rebuilt. When I had coil probs about 8 years ago....the car would start and run great but after about a half hour when things heated up.....the coil would die and i had to wait for it to cool down. This won't restart after 20 minutes. If I was to take out the carb and drain it.....re-install....it would start right up and run great !

Very strange !

Thx.....Mike

What's chances of a cracked or porous carb body casting? After a fresh assembly, everything is dry and proper and it runs fine; let it sit a while and the fuel seeps through somewhere and causes your problem. May also be a warped casting.

I'm grasping at straws here, but nothing else seemed to work. Next time you have t apart, closely inspect all of the components.

Took out the carb and removed the power valve. It was a Holley and the rounded corner were possibly preventing a good seat. The gasket they sent me was regular gasket material and not neoprene. In fact there was 2 gaskets stuck together ! So I took the other power valve and that radius is not there so I installed that and reassembled everything. Fired right up and ran perfect for 20 minutes or so. Went into town for an hour and came back and started it up and it barely started and heavy rich fuel smell and very rough !

New carb comes today or tomorrow and we'll see what happens.

As the stomach turns......!

Thx.....Mike

The more I hear about this, the less I think I was grasping at straws. A new carb should fix it.

Mike, don't forget new parts do not necessarily mean good parts. I would make sure you change your oil everytime you smell the gas, if it's in your oil thats really bad and you will be doing bearings in your motor.

I think your fuel pump is staying on and your needle and seat is leaking, filling your motor with gas.

Can you remove the top of your float bowl and then turn on your fuel pump or do you have a sight plug in the bowl? Then you can check to make sure the needle and seat are working properly.

You took the thoughts right out of my brain.....was gonna ask IF he was sure his fuel pump was shutting down BUT he never complained about a low or run down battery!!!!




ALSO Mike42.....after the 20 mins sit time, before you start or attempt to start the car have you pulled a plug or three to see IF they are wet with fuel????

Tub…..Super and Rock…….I’m hoping the new carb does do the trick. I’ve only driven the car one week since last early October ! Geez

I have a Carter electric pump and it seems to go off when I turn off the switch. Is it possible that it still pumps a bit after turn off ? I also have a Holley fuel reg set at 2.5 psi. No regular fuel pump. I have that blocked off. Never a run down battery. Always a strong start and runs great upon initial start up. After sitting is when the problem occurs. When it runs it runs really great and smooth. I have another new Airtex electric and will install that if the new carb doesn’t show results.

When I can get it started it’s like the choke is closed and exhaust pipe smokes like hell of gassy fumes and I shut it off right away.

Rock…..never pulled any plugs right after I stop it, but have checked a plug or two when cooled down and they are pitch black !

I’ll report back after the new carb is installed tomorrow.

Thx…..Mike
