It got a brief moment outside before having to sulk back into the garage with a couple more issues. Hahaha. Took a bit to get it started with all the air in the gas lines. But it’s running well now. Still need to tune better and resolve a sticking throttle on the low end. Close!
There was a crazy weird rattling sound when I let out the clutch to drive forward. And the voltage regulator is buzzing like a swarm of bees. I think it could be a ground issue…

What a blast to have it driving again! @mattressking has been super helping me get it fine tuned and running the best it can be. Missed this rig a lot.
Anyone know if a OEM belt is still available for the F135? I ordered a 9932301040 and that was definitely not right. Too wide.
Coincidentally, Anyone need a 9932301040 ?
Did you ever locate a belt? I just pulled my and noticed this part number. Doesn't look like Toyota still has it available but hopefully this helps. Keep me posted because I need one

I ended up using a NAPA belt. It would be cool to find a Toyota replacement at some point. This was the same belt I put on in 2007 when I sold it.Did you ever locate a belt?

Finally back home after a couple months of traveling! Good to be back with the 40 again. I think it was annoyed I left it alone for so long....
Walked in to see a long puddle on the garage floor leading to a nice leaking rear cylinder. I did expect this day to come soon as I dont think anyone had touched the rear brakes since I last did them in 2006! I have a set of rear cylinders from City Racer ready to go. I think its time get with @cruiseroutfit for some hardware and shoes.

32 in the garage. Perfect temp to tinker and have a naturally cooled beer. Hahaha. Thank you @rainingagain for the brew! It was great to meet you today. 
Besides the leaking brake cylinder, I have a vacuum leak that has been nagging me. Can’t find it. So I broke down and bought one of those little fogger/smog machines to hopefully find the source. Figured between the FJ62 and FJ40, it would prove it’s worth in no time.
I have been experiencing a bogging down if I give it too much pedal while driving. Choke is the only thing that helps. It’s driving me crazy!

I’ve got one of those smoke fogger thingies, handy for finding leaks. Looking forward to seeing what you find out leak-wise. Does your choke bump up the idle as well as close the Venturi?

I used a cigar for my smoke machine and blew into the port for the carb spacer. I felt so sick. That’s how that story ends.
Curious to see how it works for you and what you find.

RPMs stay the same, it just helps it accelerate smoothly.
Hahaha, live and learn...
So I had time to mess with this more tonight. I hooked up the smoke machine to the top of the carb and turned it all on. It was definitely kinda tricky to see the smoke! I used a black light flashlight and that helped visualize it. On this first pass I noticed that smoke and fluid was coming out of the throttle shaft! But I am not sure that is the issue.
The garage was 27 degrees.. so all the metal on the truck was very cold and the fog was condensing and I think that inhibited how far it traveled in the system. I need to warm the truck up and try again. Second this bogging down happened to me on this same truck before I put on this rebuilt carb and replaced the manifold gaskets.... so it wouldn't seem like the those would be the culprits... but you never know I guess.
You can see the leaking and condensed fog fluid pooling on the carb:
I think the next step is to try this again when the truck is warmed up. I am hoping its not the throttle shaft as I am not even sure that is a fixable issue...?
When it's running, if you hit that throttle shaft with some carb cleaner or starting fluid and the idle jumps, then yep, you've got a hogged out throttle shaft.
If it's not to bad, you should be able to adjust the idle mixture to counteract it. I've haven't done this myself but I've seen a few guys hollow out the hole and install a brass bushing.

Plug your pcv line and see if that makes a difference, if not then you know that’s not an issue. And since your pcv is on manifold vacuum you should be experiencing vacuum issues with it at idle if it’s failing, not just at throttle. Vacuum test?
Do you have a vacuum advanced dizzy? If so, is it hooked to ported or manifold? If ported, do you have any throttle exposure at idle? I ask that, and along with the previous question wrt your choke, because adding choke which adds throttle gives you throttle exposure at idle so when you throttle up there’s already fuel coming out of your low-speed transition carb circuit which can help with a sudden lean jump in the air-fuel ratio at throttle up, and therefore a lean bog. If too much fuel is dumping you can also get a rich jump and bog, so there’s a balance point - or range - which you’re shooting for. And also make sure the accelerator pump is squirting some fuel in at initial throttle up. Do you know if some throttle exposure was set in at idle when the carb was rebuilt? You might try a lean drop adjustment, that usually results in some throttle exposure at idle in my experience (and sometimes too much).
I‘m still right in the middle of all this with my dual offenhauser carb setup with carter carbs. So far I still need a smidgeon bit of choke on heavy load conditions so I’m not there yet. Plus it’s really cold right now so need choke for that anyhow until the motor warms up. All a PITA plus getting dual carbs balanced with each other. That’s why dual-carbed VW owners always smelled like gas.
Not sure how much of a vacuum leak problem that is around your throttle shaft, definitely a nuisance from fuel escaping. As @rainingagain said, I’d check that with engine running and spraying carb cleaner on it, that will tell you right away if it’s causing running issues. GL.

Thanks! Going to plug the PCV at the carb spacer and see what happens.Plug your pcv line and see if that makes a difference, if not then you know that’s not an issue.

I do have a rebuilt vac advance dizzy ported to the carb. I set the timing and idle mixture to get the most vacuum. Basically tuned as best as I could to try and solve the bogging but I’ll have to do it again once I figure out this vacuum issue. I’ll look at the throttle exposure. It was set to factory specs at rebuild.

When the engine is idling does anyone else hear a lot of air flowing through the PCV line? I feel like I can hear a lot. The back flow works so I can’t push air through, but I can pull air through a lot. I know it’s supposed to allow a lot of air at high rpm (low vacuum) and less at idle (high vacuum). I’m wondering if it’s acting like it’s high rpm and somehow not closing enough at high vacuum.
