Wheel almost fell off while driving…help
Unless overloaded or abused properly torqued lug nuts do not fall off. That said, GM used hub centric wheels from the factory. Many aftermarket wheels are designed to fit other brands with larger centers. Thus, they are not hub centric on GM. Just something to think about.- fast 99

Gas out of top of Rochester Carb
Doubtful, spring filter then nut. Why do you ask? Previous posts contain correct instructions. Was the float replaced? Fiber floats get heavy with age. Should never be reused. That's one of the Q-jet negatives. Some may disagree, brass floats are available, my experience they don't float the...- fast 99

Truck Size
Whatever the reason it's not me. So they develop an engine that works at higher RPM,s then to get millage add cancelling cylinders that causes all sorts of problems.- fast 99

Idle Mixture Screws Do Not Adjust Anything on 1974 454.
That's news to me didn't know that was copied. I don't like much of the new or reproduction parts out there. If you can rebuild/repair OEM stuff your better off. Just today bought an emergency brake cable from a national parts chain. Spent the next 1/2 hour trying to get it to fit. Seems none...- fast 99

Biggest jobs you have completed in the shortest amount of time.
One of our tow trucks broke a crank in the parking lot when I started it up in the morning. Was a 73 K20 350 4 spd only had PS. Needed to do a jump start about 6 blocks away. Idled the truck down and back to take care of that call. Then yanked the motor out rolled it over on another pickup... -

Can try dribbling fuel in each side of primary venturis when running. If engine slows down rich, speeds up or smooths out lean. That can also tell you if it's isolated to one side or both.- fast 99

AC Clutch Cycling Switch
AC switches are listed under switches not AC on Rock auto. If it's an original 76 system believe they had thermal limiters and bulbs.- fast 99

Ford Trash Talk Thread lol
Sooner or later, they will all break. Although I have to wonder about that one. Flat beds or tow trucks mostly loaded the opposite way, front end light. We had several GM trucks that needed frame repair. One of my SB frame was replaced entirely. Was cracked in several places and bent from use...- fast 99

Really weird air conditioning problem
Can you get a gauge set for both high and low side pressures? 100 psi assume low side? If that's the case something is restricting flow. Likely orifice tube. Not a good idea to clean it. They are inexpensive. Is it correct for 134a? Agree with previous poster on oil. Some compressors are...- fast 99

This is a coolant leak right?
Interesting, do you suppose part of that could be from numerous electrons passing to and from nearly every part of later vehicles that have OEM installed aluminum rads? Just a thought. Haven't seen to many rotted out cores. More often tanks either denature from excessive heat [low coolant] or...- fast 99

This is a coolant leak right?
Other than an originality standpoint why do you dislike aluminum rads? From what I have seen they transfer heat much better. There used to be around 10 radiator shops in this area. Now were down to 1. Getting radiators fixed and sourcing cores isn't cheap or fast. OP, appears it may be...- fast 99

Quadrajet Air Fuel Ratio
Yes, [alternate option] if lean a thin piece wire under the rod holder to raise the rods. Be sure the secondary spring is wound up the correct amount. Probably in the area or 3/4 - 7/8 turn on adjuster. Should be on the spec sheet that came in the kit.- fast 99

Quadrajet Air Fuel Ratio
If the carb is an 83 there is a small plug on top that will allow access to metering rod adjustment screw. I usually take those out when rebuilding then reinstall after carb is set up. If carb is together using a small [1/8th inch] drill into it far enough to get a sheet metal screw started them...- fast 99

Working AC again
Later 134 vehicles have insulation over the drier too. Got it from the local P&P seemed to help when at lower RPM's sitting in traffic.
