Went ahead and did some research, like I SHOULD have done before posting. Anyway, that's the Outer Vent control valve. H8PVMNT did a fantastic write up on de-smogging the stock carb.

I re-installed the charcoal canister and the vent hose, which has seemed to help with the light flooding issue I had when the truck is warm and has sat for 15 minutes. My guess is, the carb bowl had nowhere to vent the fumes and would lightly flood because of that?

I've had an issue with the truck running warm lately. I believe I may have found the problem.
The fan clutch!
Last Sunday, I went motorcycle riding with my buddies. I was driving up the trail and it started getting warm, close to the red zone. I know, the gauge doesn't tell me anything.
I didn't hear the fan at all, and when the truck is warm and running I could stop the fan with my finger...
Today in line at a fast food place it started getting warm too. Keep in mind it was 53° out.

I think the fan clutch was the culprit for sure. I may have to take it off road to see if it gets warm again...

This is VERY good advice.  WHY??.... a 20R or 22R/RE with our historical issue with an alloy head sitting on a cast iron block can cause a major failure if the engine is overheated.... even for a short period of time.

If I could only install ONE gauge in my truck, it would be a mechanical water temperature gauge... I prefer the Autometer gauges.

Thanks for the tips everyone. No engine damage has been done yet, but I would like to prevent it! Likewise, I ordered one of these. Autometer of course. Oil pressure and water temp.

That will be the best $61.06 you will EVER spend on your truck!

Just took the truck up a steep mountain grade, Parleys Canyon on I-80.
Didn't have to downshift to 3rd like I do in my other truck. Awesome! Truck also didn't overheat, nor get noticeably warm per the gauge. Which we know isn't accurate. I pulled in 4th at about 60-65 for a good 5-10 minutes.

Truck runs great, well... It occasionally has a bit of a rough idle, especially in the cold. So the carb most likely needs a rebuild. I didn't rebuild it when I pulled it off the old motor, because it ran great with the knocking motor it came off of.
Could the slightly rough (a miss here and there, never consistent) be attributed to the de-smogged Toyota carb? I know the carb itself relies on input from several emissions devices, all inputs have been capped. There is no vacuum leaks anywhere. LCE carb adapter is silicone sealed to the carb.


I'm honestly considering a Weber once I move, but that in itself is a whole can of worms.

Here's how all the plugs came out. Got about 16mpg last tank, probably attributed to carrying the heavy dirtbike for 60 miles.

Sent from my PH-1 using Tapatalk

The plugs are slightly reddish brown only on the one side. They don't look too far off to how they looked when I pulled them 1000 miles ago. Looks slightly lean. I actually had a small vacuum leak from the side intake plug. Well, it was bad enough for me to spin it out with my hand. Could this be completely attributed to the slightly lean looking plugs? Who knows. Sprayed carb clean in and under and around the intake runners where they meet the head, no change in idle. Same with carb base.

A video of it running. The slight miss is barely even noticeable.

Drilled the plug out and removed the idle mixture screw. No grooves in it, adjusted to the factory 3 1/2 turns out. I am willing to bet the lean look to the plugs is from the slight vacuum leak I fixed. We shall see. The idle is still a bit rough every now and then.

Toyota purposely put a dead zone in the gauge. Likewise, it'll never be accurate. You get out of the dead zone on your way to overheating.

Truck idles way better when warm, definitely noticeable. I now need to tackle the rough idle when cold. I may just buckle down and make my own manual choke like I've seen done before.

I think your slight lean was the vac leak.  Plugs don't look too bad anyway though.

Next up is fixing the cold start stuffs. I have my truck set up like the Canadian vacuum diagram.
My BVSV has a broken nipple, so I just have the cold start stuff capped. Which is fine, it runs good once warmed up. While cold, not so much. Especially since it doesn't have the AAP functioning, it doesn't run well off high idle until warm. No biggie. I'm trying to locate a new BVSV to fix the issue.

My SR5 cluster comes for this truck today too, that'll be fun putting in. Oil pressure SENDER already installed in the block. Just need to run a tach wire.
Now I'll have two oil pressure gauges and two temp gauges. How overkill, I love it.

I agree with H.  The plugs look good.  I don't see any lean coloring.

Rough idle at a cold start with a carb'd engine is not uncommon.

A cold start rough idle, that goes away immediately at warm up, is almost always caused by the air fuel mixture.

Ambient air temperature and air density - Relative Humidity and Elevation (barometric pressure) can also significantly affect AFR.

Why does the carb NOT have a choke or an AAP?  ???

The carb does have a choke and AAP. Both work too. The BVSV that controls both, has a broken nipple on top. I glued a metal tube in so I can connect a hose to hopefully make it work.
45° this morning, started up no issues.

It's so hard to get ahold of a good BVSV.  We should all horde them every chance we get.

Installed the autometer gauges! Looks great, but also functions good. I'm surprised with how fast the oil pressure gauge registers! Sitting at about 14-15psi of oil pressure at hot idle, which is great for 5W-30.
The temp gauge shows the engine running at 185° - 195° at idle and while driving, which is about where it should be with the stock thermostat from what I've read. Wasn't thrilled to drill such a large hole in the firewall but oh well, it was worth it! What do you all think?

Good job. I think it looks great.
Your going to be amazed at how much more active the mechanical temp gauge is when compared to the stock Moron gauge (similar to an idiot light but in the gauge form). I will tell you not to be alarmed this summer when you see higher temps on your gauge than expected. I see mine go up to 210 on occasion when pulling a long steep hill.
This is completely normal just not show by the stock moron gauge.

Thanks for the advice. I anticipate that it'll climb a bit on warmer days. I'm curious what the stock idiot gauge temp range is. The dead zone has to be from at least 180-200.
The quality of autometer is amazing!

So... I commend you for getting mechanical gauges!!... really smart.  :thumbs:

BUTTTTT..... I personally will never mount MY gauges below my instrument panel. :shake_head:

... I have always had my gauges mounted right in front of my eyes, so I can't miss any readings, and my eyes scan them constantly.

That's just my anal-ness!  :beerchug:

Having some issues getting the carb to idle smoothly at the idle spec. I can't get it to idle smooth at 700 rpm, but at higher elevation it does. So it needs a mixture adjustment.

Debating just getting a Weber, and installing a 02 sensor and gauge to tune it properly. Probably my best bet.
That, or I will make my own manual choke and manual throttle. Both would be easy to install. Weber sounds easier.
