1982 xj650

I just bought this bike from a guy who had it and said it had electrical issues he couldn't repair which I quickly resolved with a battery charge and a can of electrical cleaned and a fluid check. I got it running. However, one of the carbs the 2nd from the left seems to be dumping fuel and since it was sitting for 1.5 years i am not surprised. I am an automotive tech/ hotrod builder and I am very familiar with auto carbs like holley, carter edelbrock etc. However, not so much with these carbs. Do these work similar where the problem is most likely a stuck float or ? Any input on where to start would be good. I am going to take them apart and clean and rebuild them regardless but I would like to diag as much as possible before I disassemble them.

Any ideas would be appreciated.

Thanks in advance.
Mike

 

That sounds like a stuck float to me.

Do a search for a thread titled Carb Cleaning - The Whole Nine Yards. It's a great write up on cleaning the XJ's carbs.

 

thats what i said i thought it was and i just wasn't really familiar. Where do i find this post on the carb cleaning write up? thanks

 

Look in the XJ FAQ Suggestions forum.

 

Simple answers from an experienced mechanic new to XJs as well, just not as new--yes, they work the same sorta...did you ever deal with the old SU or Stromberg side-draft carbs, with the "piston pots" on top? These (CV) carbs work pretty much the same way although quite a bit better. As far as floats and float bowls go, conventional technology there and you probably have a stuck float or a piece of crud in between the needle and its seat.

 

Like I said I am familiar more with domestic carbs like Rochester, Carter, Holley etc. I did do work on a 1970 something Jaguar Vanden v-12 with strombergs (which are the carbs that you are refering too) Miserable to tune the first time. especially since they have different tunes for different seasons. . . Never again.

thanks for the info
