Some later model carbs. had set screws to limit the mixture screw adjustment. I would remove the plug above the screw and see if there is a set screw or something to limit the removal of the mixture screw. I had to do this on a later model AFB.

All I've found which you might already know is that is what mopar used in a 472 crate engine with 9.0 to 1 comp.

Your diagram is of a semi floating rear axle. The picture is of a hub from a full floating rear axle. Some 3/4 and all 1 ton trucks have full floating rear axles.

I think it is also connected to the brake pressure differential switch.

This was the fix back in the day. I did it a few times when I worked at a gas (service) station.

From my memory from 40+ years ago. Where I worked we had some gas converted to LP refuse trucks. Conversion involved replacing tank and lines. Installing a vaporizer. Replacing carburetor with LP unit. Also had to lock distributor advance and since the engine had valve rotator those were removed...

From what I have read in the past is you hook the ign. 1 and 2 together so you have power while in crank and run position.

Most new cars with 195 t stat will run 200. High temp t stats are for emissions. Seal shroud to radiator with foam weatherstrip. Large trucks and construction equip. do it to maximize air flow.

In my years as a government(low bid) fleet mechanic the bean counters would look at Total Cost of Ownership numbers on what they would buy. I would see manufacturers extend oil change intervals to compete against each other. Marked police cars would average 50k miles a year and sold when they...

To me it depends on what you think reliability is. They took a lot more maintenance like ignition and oil changes. 100k to 150k miles was about it until rebuild unless the body was turning into iron oxide. I always wondered why new engines seem to last longer. Is it better oil, metal use, fuel...

Yes. 3 psi. I looked up a Holley switch and it says 5 psi. Wiring should be C- fuel pump, NC- starter relay/solenoid, NO- key run position. I have seen other ones that look like a plastic oil pressure switch for a light but have 3 spade terminals. If my memory is right (CRS) we never had much...

Pressure should be lat two numbers of the part number. -10 10 psi, -06 6 psi etc.

The pressure rating should be part of the part number. In my former life we had those on diesel trucks and equipment before electronic diesels. They were wired so the pump solenoid would be energized when the starter was engaged and when you had oil pressure.

When car manufacturers started to allow play in suspension and steering parts before warrantying them is where it started. In my previous life as a mechanic we had police cars that were still under factory warranty with loose lower ball joints. We would send them to the dealer and they would set...

My easy way to check grounds. I take my 30' test lead hooked to battery neg. and DVOM neg. and touch the pos. lead to the socket of the bulb holder. On DC Volts with light on it should read zero or close to. You can do this on many components. Voltage Drop Tests works with circuit on and loaded.
