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? |

Now that... Is a problem. That sounds like a bad throttle plate or bent shaft. If these are new you need to work to return them. If not you can either examine the problem and fix it yourself (it's really not rocket science) or send them to Blackline (they bought ACE):
