Carb Sync - Spec Pilot Screw

[Jason2tpa]

That sounds more like decarbing than carb cleaning. You aren't getting anything cleaned at all in the carb by spraying down the throat while idling...

Correct, that's my point.

ya gotta remember.
the spec was for when the rig was NEW.
it does not take into account any wear on anything.
if the spec is 5/8ths and it runs well at 1 turn?
use 1 turn.
this aint rocket science.
now if you had to go 2 or 3 then something is wrong.
the 90 hp uses a pilot fuel jet and a non replaceable/serviceable pilot air orifice.
