All I can say is I can buy a fuel filter for an injected YJ:

Re: 1982 CJ8 six cylinder spark problem
Bill,
I hadn't thought about this -- so I appreciate the suggestion and
tried it.
I have two dwell meters so I tried them both.
The dwell is holding solid -- not bouncing around at all.
(Which is not surprising in the sense that the motor only has about
50,000 total miles on it; the last 40,000 using Mobil 1 synthetic.
And routine oil analysis show minimal wear.)
So -- what now; more suggestions please .....

Re: 1982 CJ8 six cylinder spark problem
Thanks for the suggestion.
I inspected it closely. No obvious sign of any problem.
So still stumped ......

Re: 1982 CJ8 six cylinder spark problem
Mike,
Didn't say this in the initial posting because I didn't think it
relevant, but original carb is gone and there is a Weber on there now.
And I don't know for sure, but looking back and thinking back I
believe I've had this problem for some time -- even when the original
carburator was still in place. (The Scrambler is driven on an
irregular basis.)
Still no joy -- more suggestions please ......
