Ok....here it is. Let's see if I have learned anything.
Problem:
After a 10 minute run today (varied between 3/4 and WOT) when I brought it back to idle it would not idle. If I kept it above 2000 or gassed it it would keep running. Changed fuel/water separator and got it running enough to get back to the dock. It ran on plane just fine...no stumble nothing. When I brought it back to idle at the dock it would idle, but as soon as I gave it gas (from neutral) it sputtered, but would keep running after a hesistation.
New plugs about 10 hrs ago....I am on the bottom half of a fresh tank of fuel (ethanol treatment added). New fuel pump within last 20 hrs....Temp is good, voltage is good, oil pressue is good, oil level is good and clean.
I am guessing I need a carb rebuilt and that my float is gummed or my "idle circuit" is messed up (whatever that is).
Am I on the right path?
Thanks!
