Cj5 Won't Start; Diagnosing Fuel Problem

I think it does, but some of it was exterior. Here is after cleaning the outside of the bowl:

Still some crud at the bottom rim and maybe in the screen.

 

That's great to know, thank you! I appreciate KW because they make the compatibility clear, but I agree the parts are not always great.

 

Okay good. BUT - does your coil throw an HT spark when you do that??? Place the output wire 1/4" from a ground to test this.

 

I don't think the coil is giving a spark. Here is a video in case I'm doing the test incorrectly: https://www.youtube.com/shorts/5NFhy1YG7ss

 

No spark, no starting. I think you are closing in on the problem.

 

Most carburetor problems are electrical.

 

Yep. Especially when working on 2 cycle boat motors.

 

Haha fair enough. Really appreciate you pointing me that way.

Does this point to replacing the coil??

 

Use a multimeter to test the coil

 

Thank you— test showed 3.6 on the primary and 9.66k on the secondary. Seems like that's the correct resistance?

I checked and cleaned the connections going to the coil and they looked okay.

 

Is the HT wire good? Solid wire is my preference but the carbon core supressor type can burn out.

 

Change the condenser, these things have a finite life and usually don’t last as long as the points and plugs.
If you can find a new one buy two, even new ones are prone to be no good!

 

Maybe so. But even without a good condenser, wouldn't the coil be firing? Bad condenser will cause points to arc, and burn prematurely, but the OP just cleaned them.

"Finite life?" I dunno, I've had many that lasted for decades.

 

I think so. It's about 16" long and showed 9.16k ohms resistance. Here's a picture of the contacts:

 

I had this same problem. Turned out it was a stripped tming gear
