- 1978 CJ 7 As delivered with 12400 miles. New battery,top, and spark plug wires, and an Earl Schieb in 1995. Zero options except for power steering. Still driving on original tires, brakes, shocks, everything.
My engine appears to be completely as delivered except cap/rotor/plugs and the heater hose I just put on. The engine runs pretty good once warmed up. I will get a backfire through the carb if I jam the throttle before it is warmed completely. My question is this- regardless of how cold or warm the engine is I am smelling a fat condition in the exhaust all the time. Either at idle from the ground, or underway from the drivers seat. The motor has 13,000 miles on it and the carb appears to never have been off the Jeep. It obviously has sat around most of its life. Do I need a re-build even though it runs good in order to get rid of this rich condition, or is there an adjustment or replacement that might lean things out. I am concerned about leaning it out because the carb backfire is usually a sign of a lean condition or timing issue. Rich is ok, lean is death. Bill
