627B carburetors?
« on: November 07, 2016, 01:40:15 PM »
Cleaned the crud off my spare carby's - found that I had one rack of 022A where I thought I had two!

So whats the straight skinny on 627B carburetors?  Visually, there are miniscule differences between the 022A and 069A carbs.

Update; found 105 mains and 40 slows in the bowls.

What can I use between them to make one nice rack?

 All the 500/550 carbs used the same bodies from '71-76 and, therefore, the same manifolds. The '77-78 models were different (and even slightly different from each other in jetting) and used different manifolds.
 All the other 500/550 carbs had slight differences in jetting, mixture screw settings, etc. I think that if you used the stock settings for any particular set of carbs they'll pretty much run on any 500/550 (yes....even the carbs that came on the F models with ever so slightly leaner jetting for the 4-1 exhaust. There really wasn't THAT much difference between them).
