WHERE ARE WE AT NOW?---DONE ANY CARB TWEAKING YET? I WAS AT A HARDWARE STORE TODAY, TALKING TO A FELLER ABOUT GAS PRICES AND HIS AND I's MPG, THIS LED INTO ME SHOWING HIM MY 4 BARREL HOLLEY AND THEN DISCUSSING PROPER JETTING ETC. ETC. WHEN I TOLD HIM ABOUT MY O2 SENSOR RUNNING MY AIR/ FUEL GAUGE. THEN EXPLAINING HOW I COULD NOT DISTINGUISH THE DIFFERENCE IN SPARK PLUG END COLORS WHEN PERFORMING "PLUG CUTS" (THATS THE NORM, FOR SELECTING PROPER JETS FOR THE CARB, USUALLY ONLY RACING FELLERS DO THIS). THAT'S WHY THE AIR/ FUEL GAUGE (OR EVEN THE VOLTMETER, SET TO MILLIVOLTS) WORKS SO WELL, NO NEED TO SHUT MY ENGINE DOWN AT CRUISE, PUSH THE CLUTCH IN, AND PULL OVER AND SNATCH A PLUG OR TWO OUT ANYMORE (I COULD SEE TOO RICH OR TOO LEAN, BUT THE CRITICAL, "GET PERFECT", IN-BETWEEN ALL LOOKED THE SAME TO ME!) MY 5 MINUTE TRIP TO THE HARDWARE STORE TURNED INTO ABOUT 2 HOURS, AS MORE AND MORE INTERESTED PEOPLE GOT INVOLVED! LET'S HEAR SOME GOOD NEWS!--THE MEDIC

CJ Medic are you still around these days? I found this thread from a google search. I read a lot of it but I'm kind of overwhelmed. I have a 1978 CJ7 that was running fine until a few days ago. No spark. I've changed the coil and Ignition Module. I've done diagnostic tests that I've found online. One glaring thing I see that I can't find an answer for is that I have 12 volts on both sides of my coil. I know I have a resistor wire in the positive lead to the coil because a mechanic put it there on a previous coil that was replaced a few weeks ago so I may need to study this thread some more to help me understand.

Davy Keith!

I'll be very glad to help you

I am a CJ guy and enjoy answering CJs the most!

The Big Guys here prefer that you start a new question, NO BIGGIE!

Start a new one (they are free) In your title/ beginning of the question

Say something to the effect of "CJ MEDEVAC help me with my CJ 7", (that may, or may not, keep the others from grabbing it up!)

I'll probably be online for another 1-1/2 hours or so tonight, I'm usually on 2car every night.

Waiting for your new question!

The Medic
