1948 Ford F1 issues

Hi everyone,
I’m in need of some help! I have a 1948 Ford f1 with a flathead V8 in it. When I bought it, it ran fine and then a few days later it would just lose power and die on me. When I would try to start it again, it wouldn’t turnover. I took it to a mechanic and had a bunch of work done to it. New carb, brakes, exhaust etc. I was hoping that within the repairs that the truck would run fine. I got it home from the shop and it continues to die on me. Huge pain and getting very sick of it. Can’t take it far from my house or else I have to tow it back. I believe it’s a vacuum issue but need some help. With the whole virus going on, I can’t see my mechanic again at the moment and would like to try and fix it myself. Another issue I’m having is that it grinds all the time when shifting. I know I have to double clutch but I had the mechanic put in a new fly wheel and it still grinds a lot making it difficult to shift. Any suggestions?? Any guys with free time who can text would be great! My number is +17203756400. Thank you! I hope everyone is staying safe and healthy.

For the first issue, that sounds like its electrical. How did you get it to start after it died? Is the battery holding a charge? For the second issue, I have no idea but someone will be along shortly.

Which transmission do you have? 3 speed or 4 speed? Do you know what weight oil in the transmission?

We need to troubleshoot a bit.

When the truck dies, does it just quit or does it lose power (and not respond to the throttle) before stopping.
Does your mechanic regularly work on flatheads?
Why was the original carb replaced?
Were the condenser, coil, or points replaced?
Has the timing been checked?
Was the fuel line checked or changed?
Does the generator put out charge?
Does the voltage regulator work?

That's enough to begin. Jumping into part replacement mode without determining the problem is a path to frustration. You would seem to have arrived at that destination.

Was the fuel tank and system cleaned. 65 years of crud in old fuel tanks.then i would move to points and condenser. Try starting fluid to see if its fuel or electrical. Then coil,timing,and starter solenoid

On the grinding into gear issue, assuming it is the 4 speed crashbox, Bob Jones has an excellent piece on his website about how to do it. However driving it is the best way to learn .

It would start eventually but then die again. After trying to start it again I would kill the battery from trying to start it again too many times. Thank you for your response.

Just file this under strange case. Maybe something to try after other easy things.
My truck would be running, for example, on flat level and suddenly die. Sometimes, while still in 4th or 5th gear, it would just as suddenly start up again, like within 3 seconds. Other times pull off the road dead. Sometimes restart would be right away. Other times it would take several tries. There were several other frequent and weird engine dies events, that would seem sort of seem related, but no real consistency as to when and where. I could never "make" it do it. The sudden dead engine syndrome was getting more and more frequent.
So I took it to the regular mechanic brothers who have 1960's Chevy Impalas (can I say that here?) for their own hobby and other toys too. At least they know how to rebuild carburetors, and are gifted trouble shooters. So what did they find?
The ignition switch was faulty. I had mine for about 30 plus years. It was an aftermarket universal type. New ignition switch, no more problem.

When the truck dies, it loses power and doesn't respond to the throttle. My mechanic is somewhat familiar with flatheads but some of you are definitely more educated. The original carb was replaced because the old one needed a full rebuild and has a little rust on it. I have replaced the solenoid and the voltage regulator. The fuel line is good but the gas tank does have a little rust in it as I switch out the fuel filter often. I was going to replace the tank sooner than later but wanted to know if there is something else causing this issue. The generator should be good! Thank you for your response.

Do you know where you got your new ignition switch?

Ok, first thing you've got to do is remove the tank. It needs to be replaced or at least cleaned and resealed. The crud in the tank is also in the lines. They need to be blown out or flushed.
