Where do you get this BS at????? It is the wrong heat range that can
cause them to foul not the brand if heat range is correct. (some
brands to not cross reference properly) You have this guy chasing
plugs when this is very likely a fuel issue as I explained above. I
guess you just like to hear yourself talk so you can feel good about
yourself rather than really help him fix problem. I have been around
Jeep much much longer than you and owned AMC/Jeep V8's far longer than
you have even owned a Jeep. Just watch and read and you might just
learn something.

Actually you kinda set idle speed and mixture togehter because when
you change idle spped with a carb you change bleed air on plates and
idle circuit some and you some alwaysm recheck settings of idle
mixture after a idle speed change.

'I' actually have worked on Jeep engines and 'fixed' a whole bunch with
fouling Bosch plugs.

Lots of folks get suckered by the hype and change out the Champion plugs.

If you Google this group, you will find the the older Jeep engines will
'not' run on Bosch plugs, period.

It is well documented and a very common cause of fouling plugs.

It is also a very common topic on other groups that deal with American
engines.

Bosch might have the heat ranges totally screwed in their book for Jeep
engines, who knows, but they don't work.
