MOTOR: 1996 Johnson 175FS. Pretty low hours and not driven hard. Motor had a tendency to stall on acceleration at the carb transition point.(going thru 1800 RPM's) I found somewhere that the initial setting for the idle screws was 8 turns out. Screwed all the jets in and backed out 8 turns. Seems to run OK when cold, but as the day goes on the stalling problem gets worse. Just a bit of choke fixes it (temporarily). Yesterday (for the 1st time) I noticed a definate lack of power trying to get on plane. After it was on it ran fine. This only happened later in the PM (91 degrees F) and the engine was fully warmed up. Do I screw the jets out farthur? How far can I go? Idle's fine. WOT fine. Checked throttle sync-OK. Used an air flowmeter on each carb-all the same. New plugs. Good gas. Will do compression ck today, but have no reason to suspect a problem here.<br /><br />Thanks<br />Tom Lea
