Re: 1995 Johnson 200HP carb adjustment
Grady204,<br /><br />Set your idle screws between 5 to 6 turns as a starting point. The '95 factory service manual is incorrect at 2.5 turns.<br /><br />The 1996 service manual says 5 turns and the '96 uses the exact same carb as your '95.<br /><br />Idle timing should range between 2 ATDC to 6 ATDC. Notice that is is AFTER top dead center, not before.<br /><br />Make sure the thermostats are allowing the motor to warm up to about 140° and that the "blow off" valve is replaced with a 1997 or later grooved one, or that a 1/16" hole is drilled in the middle of it to bleed the air out of the block.
