Mike,

Good to hear you had some sucess. I can't remember what size bolt they used on mine. The metric cure seems to have jogged my memory.

If it works I think the ford gods will be happy.

I tapped for a 7mm bolt (seemed a nice medium between the 1/4 and 5/16 taps I had) and figured that the ford gods would not be too upset about having a metric part on an original 94. Works great so far and figure if it should let go I still have the JB weld option to fall back on.



Thanks again for the ideas and guidance.

Thanks to all, grizzly that is a great idea I figure if that will not thread there is always the JB weld route, but why not start with the easiest reversible.



Thanks again, once again proving that the folks on here are by far the best crowd on the Internet.

Mike,

Another thought is that sometimes you can go the next size bolt. I had the front bolt strip out of a Holley 94, the one that holds the body to the base. I took it to my local engineering shop to have it helicoiled but they said that they couldn't because there wasn't enoungh meat but could tap it for the next sized bolt. 

Fixed the problem, made it stronger and worked until I replaced the manifold with a later one. Probably still fine.

If there's not enough room for a helicoil, then you don't have much to loose. I'd try it if it might save me from a replacement carb.

Greetings to all: Riz, I say - go for it. If the J B weld fails, you can always drill to the heli-coil tap drill size. That is, "IF" there is enough meat to support the heli-coil. Make sure the gasket surface is not warped. Draw file it some to get it true and flat from end to end. Then, excessive clamping force shouldn't be necessary. J B weld is an excellent product that should last for at least, a few assembly cycles. I too have had good luck with it. Had a slight stumbling problem when accelerating, was the throttle shaft at the bell crank lever junction of my 2100 series carb delaying the accelerator pump. J B weld shored up the throttle shaft to bell crank joint and holding good for over a year. Make sure the area is squeaky clean before applying. Nice looking truck. My 64 F100 is now in the paint shop. Good luck, JEFF...............................

I am thinking it might hold for a while. How long is the question. I had a cracked exhaust manifold on a two cylinder John Deer tractor and used Industrial Grade JB Weld on it. Held up for a year or so and then had to re do it. Finaly broke down and bought a new manifold.

According to the folks that make JB Weld once cured it is impervious to gas. I called them to see about patching a gas tank with it.

The patched tank (bottom) still holds gas after 5 years so I think the carb repair should work just fine.

I am running Holley 94s on the truck and have some of the threads for the front bolt that are stripped out.



Quick question anyone ever used JB and tapped it out on a carb body, I would rather use a heli coil, but there is not too much space. I have never used JB on zinc, but had good luck in other applications.



Any input is appreciated.
