My MC carb came pretty well set to go. I ended up getting two jets, one over and one under sized to see if they would make a difference. Mine ran great but it ran a little better and better milage with one size down.
Really there was no need for much as far as instructions, take old one off put new one on reconnect vac and fuel lines and all done.
The only thing that did not run right out of the box was the auto trans kickdown. My son was DDing it and he didn't know what it was supposed to drive like so it wasn't until months later I realized it wasn't working. I had to extend the arm a little to make it respond correctly.
Other than the HEI I put in, the MC2100 was the best mod I've done!

I got the 2150 from ebay guy as well.. I installed mine and in his instructions he says it should idle fine with just the pcv hooked up but I did it that way and it idled at 300 rpms but any acceleration would shoot flames out of the carb... not trying to threadjack just looking for any insight or if I should hook up rest of vacuum lines too??
