wow.. the jets and tubes were not dirty, they were filthy...   :crazy:

i dont know why i didnt take it out complete the first time i cleaned it. no way some carb cleaner and air pressure would get that out. i had to scrub with a screwdriver to get the most stuff off after 30 min bathing it in carb cleaner and some of the holes of the tubes i could barely even get through with a needle. i already cant wait to fire hr up the first time after this.....

There sure is....go to the Files section look in the Carb Files and on page 2 there is a PDF on carb cleaning.

Do a through cleaning, half measures will avail you nothing.

Also: Replace the float needle seat o rings, in fact, just get the carb ss screw kit and o ring kit from RPM.

How much of the crud came from the inside of the carbs?

all that dirt was on the tubes and jets. the rest of the carb is clean. anyways, now its 100% clean all the way to the last corner. turned it on, same sh*it. total hesitation. i was checking for the red plug, not sure if you meant the fuses but they are both good. now i will check the on off switch. man pure frustration...

The On/Off switch will not cause a problem with one or two cylinders. It will affect all of them. If that much crud came out of our of your carbs then I would recommend a full brake down and ultrasonic clean of your carbs. If you were not so damn far from the states I would recommend sending them to Randy at RPM. He would send them back properly cleaned and balanced close enough to bolt on and ride. Maybe you should do that anyway...

im certain i found the problem this time for real. i checked the coils but i didnt check the pickup coils and i should have, because it seemed to be something with the ignition. anyways, one of the pickups burned through, it even still smells:



anyone got a pair lying around?

If you unplug the leads from the pick up coils at the ignition box, check the ohm values at that point, you should get between 149 to 182 ohms resistance. Any less or more is no good.

Looking at the picture, I think you may have found the culprit.

Lots of pickup coils on FleaBay. I know you are anxious to ride, but unfortunately you may have to wait.

Carbs are clean and no flooding, that's a good thing.

yeah i guess no more riding before i leaving to vacation. i dont even need to get out the multimeter. it smells burned and its molten.  i only find one. strangely the ones from the 1200 only have one coil. i found this one on ebay. looks like it could fit. what you guys think?

Here's a tool that you can use to determine the assembly's compatibility between years and models on your own:

thank you. well the part numbers are not the same but if i swap the pickups itself, they seem to look the same. maybe the base is not the same size but if i just use the coils it should work or no? they look identical.

Check the rest of the wiring that goes to and from the damage. Make sure that a problem in a different location did not cause this problem. You may burn another pick up if the ROOT cause is not fixed. Or worse, burn up your FJ.
