Title says it. Got the 2150 from the ebay guy, install was pretty straight forward, new DUI at the same time, but had a nagging bog, hesitation, stumble...something, when taking off, and when accelerating with slight pedal from cruising speed.
Checked timing many times, with light, and vacuum guage as well as mixture adjust, choke adjust. Just couldnt get rid of the stumble. Checked the power valve, and it held with a vacuum pulled on it. Played with accelerator pump linkage position and holes. Still no joy.
Decided to try using some of the PV and jetting combos that worked for others here, and went from the 8.5 PV and 49 jets, to a 6.5 PV and 47 jets. Now runs like a scalded dog, accelerates smoothly with none of the afore-mentioned issues, and pulls hard to 75mph with the new 4.56's, at which point I let off. Also noticed that the smelly rich fumes are significantly reduced...really, they are not noticeable anymore.
Just wanted to share the combo that worked for me at basically sea level in Florida.
I also just purchased the new MC2150 from the ebay guy and I also seem to still be running rich. He has been very helpful and made suggestions like advancing my timing another 3 degrees, running my PCV to the carb and not teeing to the charcoal cannister, it helped some with power but still seems rich. Last night I sprayed carb cleaner around the base and it appeared to be leaking so I tightened the bolts more and it seemed to help but still leaking. Does the carb body leak some, such at the choke and accelerator pump? Should I RTV the base and gaskets as shown if needed in his directions? I had one other issue the ported vacuum on the passenger side port came out, I stuck it back in, it seems to hold. Should I send it back, leave as it is, or do some kind of repair? As far as the power valve, I am understanding from this post that the Holley PV works in the MC2150. Correct? Any help would be appreciated. It is running real good with more power than it had with the carter crap but I can hardly stay in my show with the door up while tunning on it, also getting alot of fumes in jeep while driving with hard top and doors on. Any suggestions will be deeply appreciated?
"eBay guy" is like a fart in the wind. You must be taking up all of his time to answer questions because he completely ignored me after shipping my carb a couple weeks ago. I'm not at all pleased and am half inclined to mount an internet smear campaign against him. Lucky for him I don't have near that much motivation. His product is solid but the service he promises has been non-existent.
Nor mine, but I recall in a recent thread someone pointed out he did have one listing saying "NOS." I believe that about as much as I believe him capable of follow-up customer service.
Why would you buy from this guy when there are reputable carb companies who dyno-test every carb, have a good warranty, and excellent service and support?

You are 100% right. I would not patronize this guy again and will steer people clear every opportunity I get.
