Hi Guys,
Re my other post on only being able to get to 1500rpm on water… I ran some tests (pull plugs one at a time while engine running) and found that I have little or no power to my back 3 cylinders (4,5, and 6). Thoughts? That second/back carb? I just rebuilt it. KFL motor with 2 zenith carbs. No high speed adjustable keys.
Cheers,

Switch the carbs and see what happens.

Thx guys.
After some deeper diagnosis… it was the back carb. Found a burr in the air horn that was causing the choke butterfly to stay closed. Modified (filed the burr) and shimmed the choke linkage, replaced some gaskets, and voila!
Engine running strong… but I am witnessing high oil pressure. 70psi while cruising, 30psi while at idle. I’ll post another topic…
