Setting the mixer was not a problem for me. I had the tool and then made my own. My problem was the TPS. For all the time I spent on this I should buy the tools.

Great video! Thanks for the heads-up on those two flat countersunk screws next to the venturi inside the choke horn. Locating those screws kept me frustrated for a couple minutes when doing this job the first time on my own. Also, when removing the air horn, make sure that all four of the press-fit feed tubes stay in place. The tubes will sometimes fall into the fuel bowl when removing the air horn. If you’re not looking for them it may not be obvious that one (or more) is missing. A small Torx T8 can be used to detach the secondary metering rods holder.

*You know you can (actually must) adjust the lean/rich stop screws for the the mixture control solenoid paddle by just drilling a small hole into that plug on the air horn directly above it and popping it out right? The rich stop screw is the round looking thing on the underside of the air horn just above the paddle. Check your specific model for the exact specification but typically the MCS paddle should only travel 4/32” so both the lean and rich stop screws are adjusted at the same time with a ratio of 2:1 So if you turn the lean stop screw 1/2 turn, the rich stop screw should get 1/4 turn (lean stop screw should not be turned more than 1/2 turn on the car. If you find that it requires more adjustment, you will have to go back into the carb and locate the reason.) Also, if you have the air horn off, it’s a lot easier to get back on if you back the TPS screw all the way out before reinstalling the air horn*

I have an '83 Olds Toronado with the 5.0. After adjusting the TPS and dwell, I get a Check Engine light at 70 MPH and above, which goes out in 3 seconds if I back off the gas. Code 45- Rich Mixture. It never comes on below 70 MPH. All ignition parts are new or good, and the timing is correct. New O2 sensor. The car runs great. I am going to check the float level based on your instructions here and see if that takes care of it. Will advise.

I'd be willing to bet you have a mis- adjusted mixture control solenoid. A code 45 at highway speeds that goes away after taking your foot off the gas is a classic symptom.

@@rporestorations No I don't think so. i think it is something with lack of fuel. Could it be caused by not properly working needle valve. May be valve is stacking or something?
@rporestorations Жыл бұрын
It could. I would check to make sure the float is working properly and set at the proper height. After that, work backwards and check the filter for clogs, then look at the fuel pump and lines.

I’m having problems with my 85 Buick Regal. V6. When I hit the gas and step on the break really quick car wants to almost die out. And also when it’s in park or neutral it runs good but when I put it in gear it sputters and runs real poorly!! Any suggestions on why I’m having this problem?!?
@rporestorations11 ай бұрын
Based on what you're saying, you could have several issues. I would start with a check of the basics (timing, wiring, ect). Also, make it a point to check all the vacuum hoses for leaks. That could be the reason why it runs fine in neutral, but doesn't like to idle properly under load.

How many turns out should the two mixture screws be set, before refining the adjustments?
@rporestorations9 ай бұрын
Lightly bottom out both screws, then turn them out 3 1/2 turns. That's the bench setting. It will allow the car to start and idle while you set them. I'd also recommend watching this: kzbin.info/www/bejne/rJCTYYKhgJ11d8ksi=EoSJCqk00sVcutJS

Hi , I was hoping you could help me . I have a 1987 cadillac brougham with the 5.0 olds and have the tps code so I changed it and I cannot get the voltage to change when adjusting the screw . Any suggestions sir ?
@rporestorations Жыл бұрын
The screw has quite a lot of slack in it. It might require a lot of turns before you get enough tension to change the voltage. What kind of readings are you getting now?

I have the same carburetor in my 1987 Chevrolet El Camino, in the morning it starts very well and the car runs very well, the problem is that it smells a lot of gasoline and smokes a lot, the gases that come out of the muffler are exaggeratedly horrible, but it accelerates Very good, what could it be?

Is there a way to measure to see if the MCS is off before taking the air horn off? It would save a lot of unnecessary work if the setting is already correct- if it ain't broke don't fix it.

So I’m trying to adjust my TPS and the issue is that I have to set my low voltage to .50 when I set it and start up the truck and accelerate and turn the truck off and recheck my TPS voltage it’s either up or down to .30 or .70 what can be the issue please help

I would strongly recommend putting blue lock tight on the threads when you adjust the TPS. Fully remove the adjustment screw and place a drop or two on the threads. Adjust to the correct voltage, and let the truck sit overnight before starting it.
