Weber progression hole differences
Lately I picked up a set of IDA's all have the made in "blank" casting. Assuming Spain, all have the 3 progression holes. Three of them match, the 4th is drilled differently, but with 3 holes. See pics. When the butterfly is closed on the 3 that match,it covers the bottom hole. On the 4th carb with the different pattern, the bottom two holes are covered. Am I screwed? Or can they be filled and correct pattern established?
