MC2100 Swap
I have a '88 YJ and I just did the MC2100 carburetor swap. When I
pulle the original air cleaner off there were 2 large hoses that go to
the "Pulse Air System" and I am wondering what to do with them? Do I
plug them? Do I put a filter on them? People who have done this, what
have you done?

Re: MC2100 Swap
I put a Weber carb on my 87YJ. Weber recommends
drilling holes in the air cleaner box and plumbing them in
there. They say those lines need filtered air.
Those lines inject air into the exhaust system for the
catalytic converter to function. What you do with them
depends on the pollution/smog requirements of your
locality. Where are you?

Re: MC2100 Swap
You can hook them up into an air cleaner for the 'visual' part of the
emissions, but they will not function. I would do this so it looks as
stock as possible.
Once you removed the carb, you put the computer into 'limp home' mode
which shuts down all the sensors and clamps down on the timing advance.
I recommend you do what is known as the 'Nutter' bypass which just hooks
the ignition module directly to the distributor so you now can set the
timing and have the advance work properly. It also gives a sweet 25%
seat of the pants power boost. I use 2 new wires for the bypass and tuck
them into the loom rather than mess with he stock wiring. The YJ has
different colors than the CJ the Nutter was written for. Here is a link
on it:
