Here is the info on how to do the nutter by pass http://www.jeepforum.com/forum/f12/p...bypass-476720/
and i prefer the mc 2100 with the 1.08 vent
and if you do go with a mc i can send you the set up instructions by fax or e-mail.
the stock carter carb is a pain but if you do the nutter by pass and set the metering rods and air-fuel it will work better until you get a new carb.
But do the nutter by pass first no matter what carb you go with.
it will make a hugh difference. the motor will rev out faster , smoother and farther
you will get better mpg and it will start a lot better.
And if you add a cdi dist. with goo plug wires then you will have a very smooth running motor.
feel free to give me a call no matter what you go with if you need help .
