I played around with the carbs some more today - nothing like inhaling fumes and exhaust as you lean over a hot engine on a hot day...

This is the second time I've sync'd the carbs, and again I found that I needed to significantly open up the air screws on cylinders #5 and #6 to get them sync'd to #4 and the left carbs/bank.

By significant, I mean I had #6 opened about as wide as it could go.

Is this unusual? Is it possible I have something clogging my jets causing these two cylinders to draw less air?

BTW - the PMO's I'm using were purchased lightly used.

Thanks, Gordo
