There were no bushings where the throttle shaft goes through the housing, and the shaft moved around about .05" from wear...probably due to a heavy return spring. Unlike the old Holley, there is no baseplate to replace, so it would have been a nightmare to fix. Hopefully Summit corrected this situation.
Like any carb they are easy enough to rebush.

4010 is an easy carb to modify and Summit has done a great job to fix the little "woes" and produce an even better, more tuneable carburettor.

I have no issues. People either hated the 4010 or loved them, like anything else the people who hate something are going to speak louder. I have a racy cam on my 351, and like the carb before, I had to clean it, rejet it and tune it...
I've had 4010 750 DPs on 300 - 400 CID engines with great success. A very underestimated carburettor for those who aren't used to change.
