I just bought this Jeep a few weeks ago and it was running just fine.
About a week after I got it, I realized it needed a new carb as the
float was stuck in the current one. I replaced the carb with a rebuilt
one and it was running just fine again. Now, maybe two weeks later,
all of a sudden when I turn the ignition off when I get home, the
engine shuts off then maybe a fraction of a second later it starts
shaking like it wants to start up again (sort of like bucking?). I
have noticed the shaking is directly related to the amount of time I
have been driving for. If I run out for a few minutes, it might not
shake at all when I turn it off. But if I go for a half hour long
drive, when I go to turn it off, the engine starts shaking. Any ideas
what could be going on? Any help at all would be greatly appreciated!
I have a 1986 CJ7 73K, 5 speed manual with an inline 6. Thanks, Jason

 

It's dieseling, because the idle is too high. Usually the choke
fast idle cam linkage is sticking. And of course that cheap gasoline you
trying to wean it on.

Bill,

Cheapass gasoline causes pinging under load, not dieseling.

Not a fix but this will stop your problem. When you shut the engine off
leave the Jeep in gear and let off the clutch.

When I shut mine down I always leave it in gear and will usually let off
the clutch as I switch the engine off, it's a habit I've had for years
and do it in all my vehicles. It positively shuts the engine off and
with the vehicle in gear there is little chance it's going to roll
either (except in a overdrive equipped Studebaker, but that's more than
a little off topic!).
