Sounds lean on the primary side, and most likely is with that jet rod combination.  Might want to try smaller primary metering rods, and even go up on the jet size one number....Cliff

Cliff,

 SUCESS!!  We spoke about the marine carb last week with 67 jets and 44B rods - way too lean indeed.  Installed the 39 rods you sent and water tested today.  The boat runs perfect!

 Thanks for your help, your book (which after reading 3 times and working on these things for a few years I am finally reaching a novice level), and most of all thanks for your commitment to your work.

 Back in the day (late 70's), my father told me about the trips he was making from Anderson, IN to Rochester to work on the E4M project. He was a sales engineer for Delco Remy. It was their solenoid and they were pretty heavily involved.  I was 6 years old - probably should have paid more attention to what he was saying!

Cliff Ruggles:
Good news!....Cliff
