1969 with 351 Windsor stock engine. Once it reaches 1,500 rpms why do the tach & engine jump up and down?


If this is a points type ignition, check for excess play side to side in the distributor shaft, and also for timing chain slack--easily tested by removing dist. cap and rotating engine back and forth with wrench on crank pulley bolt. If rotor doesn't move immediately as crank turns you have loose timing chain.

How to adjust the fuel and air mixture on a 1982 ford 4.9 six cylinder, carter carburetor.


There should only be 1 screw located at the base of the carb facing outward.

The method I use requires a tachometer. If you don't have a tachometer then you can use the "by ear" method, though it's not as accurate.

With the engine off, start by turning the screw all the way in, then back it out 1 and 1/2 turns. This usually give you a baseline to start with.

Start the engine and get it up to operating temperature, make sure the choke is fully open, and have the air cleaner and all vacuum lines installed.

Using the tachometer (or ear) turn the screw (usually out) until the RPMs increase. If they don't increase by turning the screw out, then try turning it in.

Eventually the RPMs will stop climbing while turning the screw (as said earlier, usually out).

THEN turn the screw the opposite direction (usually in) until the RPMs JUST start to drop off. That should be real close to the optimum setting.

This setting is ONLY for the base idle air/fuel mixture and is NOT for anything else.

Hope this helps.

Timing on a 1990 Wrangler with a 4.2 liter


4.2L 6-Cylinder

1. Set parking brake. Shift automatic transmission to Park or manual transmission to Neutral. With A/C off, start engine and attain normal operating temperature.

2. With ignition OFF, connect an ignition timing light and a calibrated, expanded-scale tachometer.

3. Disconnect 4 " and 10 " Hg (CEC System) vacuum switch assembly wire connector (located at top of valve cover). Disconnect and plug distributor vacuum advance hose.

4. Start engine, increase engine speed to 1600 RPM and check ignition timing. Adjust timing to specification listed on Emission Control Information label (if necessary). Tighten distributor hold-down clamp and recheck ignition timing.

5. Turn engine off and remove timing light and tachometer. Connect No. 1 spark plug lead, if disconnected. Unplug and connect distributor vacuum advance hose. Connect vacuum switch assembly wire connector.

NOTE: If timing light has an adjustable advance control feature, turn control to OFF position.

Timing is set per the emissions tag under hood.

When you hook up the scanner, make sure the ignition is off. After you plug it in, turn the key to "run".....do not start the car.

Car starts and idols fine but once you get it to 4000 rpm it cuts out and then every time you hit the gas it will accelerate then cut out. it doesn't die out until you do this for a long time.
