Does anyone have the pilot screw turns out spec for 2004 2 stroke 150TXRC?
My Yamaha service manual has the other carb spec's, but for some reason doesn't have that line.
Seloc manual has 3/4 to 1-1/4 turns, which sounds like it may be about right but need to verify.
Carbs were rebuilt 2 years ago (not by me) for the first time since buying new, so not sure if they were set back to factory turns out or if the mechanic tweaked it to his liking. Ran OK last year. But this year has been sneezing / stalling at idle (pain in the butt when docking). So figured I'd see if resetting the pilot screws helps any. All fuel filters have been changed as part of regular startup and fuel pumps are only 2 years old. Runs pretty well otherwise, but did lose 300 rpm at WOT. Now maxes out at 4800 with still more throttle to go that doesn't do anything. That's probably a sign that carbs may be gunking up, as I haven't been able to use the boat with any kind of regularity this year.
