New carbs- one barrel pulling in too much air Options

[tornik550]

I purchased brand new weber 44 idf carbs from redline weber recently. I set everything equally between all barrels. I set the idle stop at 1/2 turn on both carbs. The engine started right up. I disconnected the linkage. Checked the air flow with a snail. Equal readings on cyl 1,2. Cyl 3 was pulling in so much air it was off the chart and cyl 4 was barely getting any air. I backed off the idle stop completely and I am still getting a huge amount of air in cyl 3 and almost none in cyl 4.

I took the carb off and visually inspected. Everything appears normal. Both butterflies appear closed.

FYI- I am certain that this is not a valve or cylinder problem. Everything was fine with my previous setup.


Any ideas?

I bet you got the set that I sent back to Redline! They never would work for me. Check the floats and see if they are stained or flaking off small pieces of the float. If they are send them back because there was something wrong with those carbs that I just could not make work. I tried a huge number of suggestions from Redline and the members here and the carbs just would not work! If Weber and or Redline is sending out carbs that you have to fix their manufacturing flaws is that something you really want to do?

By the time I was done, I wished I had just purchased a known used set. I had another $250 in jets and Venturi's and a whole lot of time invested before I sent them back.

Regardless of what Redline says, 36mm Venturi's are too large in the 44s for our engines. When I went to 28s on the second set they began to work well.

PM me if you want the details of my experience.
