84 CJ7 won't idle
I've got 84 CJ7 that won't idle when it warms up. It has a new looking
rebuilt feedback style of carb on it. The timing is good. I've read
some older threads about the carbon can and intake manifold, which I
will check. I called the Jeep dealer and they said Chrysler doesn't
make carbon cans for them any more, not that I know that I need a new
one. It doesn't look in the best of shape though.
Can any one provide me with a proper layout for the vaccum hoses? That
thing has a country mile of vaccum lines on it. I've got a feeling that
someone has them all screwed up. I can't read the one under the hood
anymore.
Thnx, Curly

Re: 84 CJ7 won't idle
If the canister is the trouble, it will normally surge at idle and puke
oil into the air filter.
The most common cause of bad idle is plugged up idle tubes. Their
crimped metered ends block up and need a 'physical' reaming out
preferably with an oversize added. The physical part is an issue with
rebuilt carbs, because it is normally a 'Big' no no to ream out carb
parts so they rely on chemicals. Unfortunately chemicals just don't do
it so lots of rebuilts come broke already.
One sneaky one that can block them is a dirty tube from the filter to
the carb.
Here is a link on cleaning them out:

Welding supply shops sell metered files and mini drill bits for cleaning
torch tips that work well for this.
