I have heard the same thing about the Webers being a pain to tune and having to tune them more often than the MCs. My brother swears by the Webers but when I did the nutter bypass three years ago, i read about the MC's vs the Webers and chose the MC -- the reason I am thinking of a Weber, is because they are new and not reman'ed correct?

I am usually the type to repair (or have repaired) what I have and not spend the dough -- I'll have to see if I can find someone in my area to rebush the shaft with new brass ones. i will let you all know how I make out.
Thanks again everyone!!

I would not worry about the bushing. I believe if you check others with a spray, they will all leak in that area. I would stay away from a Weber, never had much luck with those. If you do a internet search, the 2150 is about one of the best carbs ever built.

I have seen a little fuel leak out of the throttle shaft on the driver's side of carb when manually working the throttle linkage while the engine is off -- she runs great but only idles great sometimes and other times not so good -- I have to re-tune and make sure choke is working properly and will report back. I know all my vacuum lines are in good cond. and have a new base gasket. I am thinking I may have made a mistake when re-installing the carb after removal and power valve replacement: I had a spare base gasket thankfully, and when I installed it I think I should have cut out the piece of the gasket in between the two barrels -- I left it there and think it may be causing a prob?? It didn't seem like there was anywhere for it to seat to (the gasket part in between the two carb barrels) and I think my old gasket from the original install was cut-out there?
Thanks again everyone for your help here!

"I have seen a little fuel leak out of the throttle shaft on the driver's side of carb when manually working the throttle linkage while the engine is off --" A lot of carbs do that.

Thank you alabamaranger for the info.! I re-tuned the carb from cold, starting with setting the choke and then idle speed and then adjusting the air/fuel screws with a final tweak on the idle and she is running and idling like a champ!!
Definitely was the power valve failure causing it to run [super] rich and the final tuning that evened everything out!! Another testament to the MC2100/2150 carbs! And I was thinking of switching to a weber!! Glad I stuck with it and with all of your help made it possible!!
Happy wheeling Brothers and Sisters!!

Glad you got it fix. On the Weber, you are operating off a 1 barrel carb until you get into the throttle, than the secondary barrel opens up. I remember Ford Pinto's had those Webers and never did like those. We had a Weber on my son's Jeep and we put a 2150 on it and the Jeep came alive with power. He said he will never go back.
