Hi everybody,
The post is a bit long but please bear with me, this has been a LOOONG time coming.

I’ve been on mud for about 10 years now, ever since I first bought my 40 up in Anchorage Alaska when I was stationed up there. Began the partial restoration process (nuthin too fancy) drove it a bit while I was up there, but It never ran great.

That was the preface, here’s the meat;
-07/‘75 FJ40, hardtop (50 next month!)
-Holley 500, (Recently installed an Aisin)
-HEI (cheap) conversion, swapped from old vac retard distributor it came with.
-Rebuilt 2F, 4 spd and T-case
-countless other new parts

Im looking for some direction on this thing, I really, really, REALLY just want it to start and run OK. It vehemently refuses, regardless of how much cash, time, effort, blood, sweat and tears I throw at it.

This restoration has fought me every single step of the way. Every single part and process, seemingly intentionally goes out of its way to be as difficult as possible. Which is ironic, considering the Fj40 is really just a tractor with a body on it. It should have been an enjoyable process.
I won’t even get into it any further than that but I’ve also had problems with almost every person I’ve hired to do anything with it, from the engine rebuilder taking months to finish it, the body repair guys that gave it back to me partially done and in pieces (missing rare parts) and after $4000 paid to them over 4 years, rare mid-year parts I’ve had a hell of a time locating, etc, etc, etc

So, FINALLY my questions are:

1. Why does the secondary linkage hit my intake manifold? (See pic) The engine is a ‘75 2F, the carb is a ‘77, should work fine. The carb spacer is in the correct position from diagrams I’ve seen. What gives?

2. I’ve never got the Holley to run well in all these years, so I purchased the OEM Aisin and did a rebuild with Keyster parts. I know my way around carburetors but I’ve read that the 77 to 79 is notoriously difficult to tune. Great.

3. My cheap HEI distributor wobbles. I’m guessing the shaft wasn’t machined perfectly round. The bottom of the shaft seats perfectly in the oil pump but I still don’t trust the set up. I’ve read that I need to put a 60 series distributor on it. People want $400 for a used one on eBay so if I’m going to put the time into tracking one down for a reasonable price I want to know it’s the best one for my setup. Otherwise, what other HEI set up will work with my OEM 77 carb?

I’m looking for ANY help anybody can give me with this thing, I really don’t want to sell it but I’m so unbelievably frustrated with this truck I’m at the point where Id almost rather just watch it burn to the ground than sell it. I’m sure a few people really have been in the same position with some project they’ve had!

If you need more pictures or info, please ask and I will supply. I have scoured the forms for information, hours, and hours of digging, and there’s multiple solutions to every problem.

With what I have, I am mostly asking for advice, what were the other 40 owners do in my situation?

Thanks in advance

From the looks of it your missing the heat shield with spacer piece under the carb. then you will get your clearance issue resolved.
Looks like you are using an early style intake manifold. Im sure someone will chime in if I am wrong.
have you tried a different HEI distributor?
 
Get rid of the gm dissy.
Throw a city racer new oe dissy and pertronix at it.

I will look into the heat shield clearance issue, I figured it was some type of spacer that I was missing.
So an HEI will work with the factory carb? It would be nice to go Toyota, but at this point I don’t care. I’ll just buy a decent quality HEI conversion unit.
 
The oem electronic distributor on my 79 had a wobble too. Took me a while to figure it out. But once I did, I located a FJ60 ignition setup (big cap distributor, igniter and dimpled pushrod cover) from members here.

The upgrade made a huge difference in my case. Those big caps have a solid reputation for dependability, and that water resistant cap is nice too.

You've got lots of options for that 2F.

Good luck getting your current issues squared away.

Hey, most of us have been where you are. I suggest that you walk away from the project for a few days and come back with a fresh perspective. You have a nice rig, you just need to dial it in. There are several carb and distributor gurus here on Mud and I'm sure they'll weigh in. First though, you need to do a baseline check which consists of:

1. Compression test - You're looking for consistency across the cylinders. (I know that your engine was rebuilt but there could be problems anyway)
2. Timing - Gotta make sure that the spark is happening when it should. Set it per the specs in the FSM to start with.
3. Voltage to coil - Make sure you're getting at least 12 volts to your coil. Test with a multi meter.
4. Vacuum Leaks - Start it and spray carb cleaner around the base of the carb and at every vaccuum connection (including the brake booster and the intake manifold to cylinder head joint). Listen for a change in RPM which indicates a vacuum leak.

You just can't tune around these issues. Once you're sure that the above points are good, it should be fairly easy to get the rest dialed in.

Have several of the new OEM points distributors in stock here. They're about $300 and would be a drop-in for your 75, we also have new proper OE coil/ballast resistor setups in stock as well
If the distributor is loose that is will definitely screw things up.
Several other easy issues in your pics.
1. Missing carb spacer (have new in stock along with proper OE studs/nuts)
2. Fuel filter between pump and carb (this line should be metal all the way to carburetor. We make stainless steel replacement line for this

I have not read this entire thread. I read a little.

I’ll send you a good running Weber setup and my hei distributor that was pulled from my running F motor if you want it.

Mine died a head gasket death and is getting a V8. It ran great 2 months ago with said parts.

Reach out if you want them. I just want to see another cruiser back on the road.
 
Thank you everybody for all the responses!
Cruisermatt, I’ll probably hit you up for all those parts you mentioned.
clrussel: appreciate the offer! I’d like to run the carb I just got, Ive read good things about the Aisins.
Msapers: I was actually in the middle of going through that list you gave me when the radiator fan decided to snack on my vintage snap-on timing light (with adjustable dwell). Sucked it right into the radiator, punched a nice hole in a few tubes and sprayed coolant all over the motor. That’s when I walked away for a while.

Dude. I don't blame you at all. That sucks really hard.

She’s fighting to stay parked, don’t let it win.

Good call on the walk away..

I once spent 1/2 a day installing a new front wiring harness on a 63 Vette. Had just reconnected the battery, was cleaning up and dropped a wrench that landed perfectly across both terminals…🤯⚡⚡

Spent the afternoon at the cold snack dispenser. Didn’t help the harness but it didn’t hurt it either.

Did the Snap-On survive the engagement?
