Mine wont atay running with both flaps open like that. Got some black smoke blowing out the pipe too

You perv! How could you finger that poor innocent Yota? *DISGUSTING*

I have your same set up I deleted all my vacuum lines but the two to the distributor and mine just flat out will not run right it tuns terrible. How did you get yours to work and why did you take the choke assemblies off the side

It's very important that you block off all unused vacuum lines. If you have disconnected the "fuel cut solenoid" on the side of the carb, it will not idle. If you left it but disconnected the vacuum switch on the passenger fender, it will cut out above 2200 RPM. The vacuum advancers on the distributor should not be required to idle, so you can disconnect those for testing at idle if you want. I removed the choke as it did not work so well, and wanted to get rid of the electrical connections to the choke heater. The manual choke works fine for my needs.

mct75 the fuel cut is the thing on the side you made a small plate for? With the three little machine screws in it

That is blocking off the "outer vent control valve" which opens up the carb bowl to a charcoal canister when the truck is off. The FCS is facing the passenger side firewall and has two wires going to it. It's replaced with a small bolt.

I don't have the truck anymore, but the only lines you need are the two that go to the distributor. Learn what each vacuum system does and how it interacts with the engine, then remove it all and plug everything except those two distributor lines.

I've looked everywhere and can't fone shit

does it pull cold with no aap? bolt in the fuel cut solendoid? no dieseling? I did the same thing except a vacuum source to the top choke diaphram and a T to the top of the prong BVSV so that switches when warm to break the cold idle.

I live in a mild climate, but in the winter time around freezing temps it would stumble for a few minutes if you stomped on it. I was able to gently open the throttle and avoid this. After it warms up for ~5 minutes it is fine (and the BVSV would have isolated the AAP anyway by that point so it's out of the equation) Yes, a bolt in the FCS. I actually had to do this once I removed the vacuum switch on the PS fender. There's a deceleration fuel cut system that was causing it to stumble on the highway. It would sometimes diesel, but if the idle speed was adjusted properly there were no issues. I would normally keep the idle around 650 or 700 and it was perfectly fine. On warmer days the idle will increase so I was having to adjust it every few weeks. Not a big deal, especially because my idle screw was loose enough to turn by hand! The manual choke works so much better than the automatic one ever did. I found that if the temperature was above 50 or so, just pumping the gas about 3 times with no choke was sufficient to have it fire right up and run great.

mct75 that helped. thanks a lot. I was thinking about manual choke conversion just for fun but sounds like having a bit more control would definitely be ideal. right now I can't get the gas to lift the float up to the sight unless I have my aftermarket electric pump straight to the carb. two stock manual pumps I have seem to be a bit weak. however the electric is a bit too strong at 5-9 psi... finally going to put a T after the fuel filter and back into the existing return line and stop using the stock pump altogether. if I get my power without hesitation then I'll know it was fuel delivery to the carb

@mct75

It sounds like you might need to adjust the tabs on the float. That sets the level. At idle it only takes like 0.25 PSI to keep the fuel in the bowl. If you're having to jack up the pressure, the level might be too low and you're just relying on fuel forcing itself past the float needle. Definitely get that sorted before you start adjusting anything else.

@modifiedvai5975

mct75 very interesting insight. it'd explain why my dads iffy on my weak pump idea. thats not a lot of pressure and I know the stock one I have is pushing more than that so... the bowl should fill unless that tab is not calibrated.

@mct75

7 жыл бұрын

For reference, if my bowl was empty I could just take the fuel line off, and pour gas down it and the bowl would fill up from the gravity alone. If the level isn't right when the engine is off/idling it probably isn't the pump. You can always take the line off and crank the motor over, just see what comes out. Be careful though.

Yep, the secondary butterfly was fused shut so I removed the linkages and some of the choke crap for that side. Engine ran great until about 3000 RPM then started to fall off (without the secondary it was hurting for air) but you don't need to be redlining a 30 year old truck anyway.

​@@mosesandrews4381 Hey man, I don't know about your truck in particular, but start by identifying where every vacuum line goes and what it goes to. Chances are, you can remove nearly every single vacuum line on the truck and it will still run. The distributor may have a vacuum advancer (the 22r has two actually) and maybe a fuel pressure regulator that are critical and not emissions related. Identify each component with a vacuum line and go from there. EGR will be a big one (lots of vacuum lines and a connection to the exhaust) and maybe a smog pump. (big ugly belt driven thing with large air hoses) Good Luck!
