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? |
