Post-MC2150 swap: to Nutter or not?
I performed the MC2150 carb swap last weekend. Everything went on flawlessly, I didn't have to adjust anything. Per the instructions (I bought it from the ebay guy), I hooked up the system to get it running, but didnt do the Nutter bypass (it says to get it running, do the bypass AFTER you make sure it runs/idles).
Anyway, I let it warm up and drove it around the block and at highway speeds. It drives perfect. No misfire, sputter, hesitation, etc. So my question is, do I need to do the nutter at all? I subscribe to the "if it aint broke, dont fix it" philosophy. I spoke to my mechanic buddy (a real, certified, mechanic...not shade tree) and he said if its running fine to just leave it alone. Always looking for second, third, or fourth opinions, I contacted the ebay guy. He said this:
"I have run many setups w/o doing the bypass, however... I still recommend it. It will eliminate the computer and problems down the road from the equation. I say do it."
What "problems down the road" is he referring to? I have the proper wires and also have a timing light, so I can do the bypass whenever. Basically, Im looking on what the cons vs. pros are in this matter. I havent been able to see what my MPG is with the new setup (since it was just installed and the jeep is a weekend vehicle), but I have noticed that throttle response, idle, and "powerband" is much better than the Carter. Plus, no more hard starting.
