I just bought a 1979 cj5 jeep. Only thing wrong

We do not have wiring diagrams here at fixya, the manuals are copyrighted material I did find this one picture with numbered wires that may help you hook things up.

Firing Order: 1-5-3-6-2-4.

Check thius FIRING DIAGRAM

Hope helps.

Adjust your mixture screws. If you're not mechanically inclined take it to a shop. Worst case scenario you need your carb rebuilt if the float is toast.

Generally if you bend the washer up against the flat side of the nut they generally don't move. Not sure what you could be doing wrong. It doesn't generally take that much to hold that nut from turning.

Willys Overland merged with Kaiser and became Kaiser Jeep Corporation in 1963; AM Motors Corporation bought Kaiser in 1970. There is some interesting info at willysoverland.com

Please don't add brake fluid to the engine, you'll ruin it. Brake fluid is added to the Brake Master Cylinder.

Hood open, viewing your Jeep from the front, (Facing the windshield)
The Brake Master Cylinder is on the upper right, mounted fairly close under the windshield.
(If you have Power Brakes it is mounted on a Power Booster. If you do not have power brakes it is mounted directly to the firewall)

This link below will show you what it looks like,

This link shows what the brake master cylinder looks like, not installed. You are looking at the back view of it.
From the mounting flange that has a hole on each side, to the tip of that rod sticking out, is a view you will not see.

The photo is to illustrate the top cover, and the wire looking device that holds the cover on.

Viewing the Jeep from the front, the wire device you see is moved to the ->Right.
A common tool used to move it would be a sturdy flat tip screwdriver.
It is very stiff to move, but be sure you are trying to move it the correct direction.

When you go to fill the master cylinder the proper level for the brake fluid is one-eighth inch below the rim edge. (1/8th inch)

You will see two compartments. You will also see that the master cylinder sits at an angle. It's angled toward the back. The back edge of each compartment's rim edge, is what you use to judge the brake fluid level. (1/8th inch below that edge)

With the engine off, Look down into the carburetor and move the throttle. If you don't see a healthy squirt of fuel. the accelerator pump has failed. The carb may also have deposits in the fuel passageways and may need an overhaul including a good soak in carb cleaning solution.

find the play! Start at the begining, steering column lower brg,then check shaft joints for play then gear box then front end.
