Re: Rough from 1000-2300 rpm
Geez. You too? <br /><br />I was just about to post same thing. I have a 1989 120 on a Mako 17 I just bought last weekend. When I first took it out, I was a little underwhelmed at the power until 1 or mebbe 2 more cylinders decided to fire and woke me up. Acceleration just about threw me out of the boat. Took mebbe 10 seconds for me to finally reach the throttle while boat was airborne at 35 knots and accelerating (it was a lumpy day here on the Left Coast). <br /><br />Engine's running fine at higher RPMs, smooth acceleration, no coughing, sneezing or runny nose typical of timing problems. Plugs are all correct and uniformly clean, but a little moist. At trolling and idle speed, engine runs rough. I've got fresh gas and oil in it, so I'm beginning to think, after I check timing and spark intensity, mebbe I need to look at the carbs. <br /><br />Any thoughts would be appreciated.
