    Posted: 11 Apr. 2015 at 5:33pm
I'm always thinking my idle is too fast or too slow. I read it's supposed to be between 600-900 rpm? How do I set it?
I know where the idle screw adjustment is but how do I know it's at a certain rpm.

Thanks.

Do you own or have access to a Dwell/tachometer and a Vacuum Gauge? Without these tools whatever you do is just a WAG. With these tools and the information found at this link -
and provided all is well with the rest of the motor, you should be humming right along very soon.

I just noticed the heading of the article say without a timing light. Could I just use a timing light?

If your timing is close, the procedure will bring it in much better and you won't be bending over, hanging upside down to see the marks on the flywheel.

A basic tune up tool kit should include
 
An inductive timing light
A Dwell Meter TACH combo
A set of feller gauges .001 to .040
A spark Plug gap tool that covers .020 to .060
 
A VACUUM GAUGE and the necessary tubing and tee fitting to plug into a manifold vacuum port
 
A SHOP MANUAL for the vehicle you are messing with.
 
Beyond that for a Willys a pair of 1/2" open end wrenches (for the valves) one can also be used for the distributor hold down
 
A Spark Plug Socket to match the size of the spark plug being used
 
A little tube of anti seize compound for the plug threads not only protects the treads but will actually help seal the threads.
 
Advanced kits should have a screw in compression gauge
A VOLT OHM AMP meter is also nice for any electrical issues.
 
Almost any pawn shop will have used versions of the timing light and Dwell/tach pretty cheap.
 
With the above tools and properly following the manual you should be able to get your Willys into as perfect of tune as its physically possible in a couple hours (depending on having to mess with the valves) And less then a 1/2 hour if just messing with ignition tuning once you know what your doing.
 
When I was a kid and just starting to drive and just coming out of the tearing the mini bike apart every other week my dad would have me run through the tune up on the Willys about once every two weeks. By the end of that first summer not only was the little 134 L purring like a fat kitty but I knew all the basic's of auto mechanics and how to properly tune an engine for the best performance.

Boy does that ever bring back memories Smile.  I used to love to watch my Dad tune his (our) '47 CJ2A L-head with a vacuum gauge, timing light and his left ear.  The right ear wasn't so good as it was the ear he used while on the phone at work all day ( LOL  ).
When he finished, that little baby would purrrrrrrr and had smooth power everywhere!!!  Sure am glad he took the time to teach me how to work on the Jeep.  I never learned the ear thing quite as well as him, but I do ok.
