So I ended up completely disassembled carb again. Still no sign of any crud or residue anywhere.Slow needle screw is perfect. Removed Walsh plug, perfectly clean chambers and passageway. Sprayed all passageways with carb cleaner. Reassembled with all OMC gaskets and packing. Adjusted float just a little hoping to allow a little less gas to flow. Still seems like it is slightly flooding when not running fast. Throttle plate is closing completely.
Reed and chambers are perfectly clean.
The throttle cam does close plate at the idle position. And opens fully at fast side. Seems correct to me but I have no information on setting it.
Tried to start with needles at 1 1/2 out. Nothing. Started to fire at about 1 turn out and ran when set back slightly less than 1. It ran about 4-5 minutes, did adjust high speed needle to a peak good smooth speed. But then quit and I could not even try to get to a slow speed. Would not run again.
Maybe tomorrow I can try to adjust slow speed first. Don’t know what else to try on carb.

I am wondering if heat is the problem. It is spraying water on both sides when it does run, but I don’t know if it is right. I put in new impeller kit.

I appreciate your thoughts on what to try now.
