Re: hard to start, but after that it's 1key turn and go.
I have a 1979 Johnson 150 V6. Very similar engine to yours. There is a manual choke lever you can engage at the carb. If you take the cover off of the intake, you can see if the flaps are closing when you engage the selonoid at the key. There is no flap on the the top carb on my engine.<br /><br />My engine is the same as yours. First crank of the day is tough, everytime the rest of the day it is an instant start. I just figured it was age. But since joining this board, I have paid close attention to the quality of my oil and the precision of which I mix, and have gone from 93 to 87 octane, and the problem is getting a little less frustrating. I also pump as much gas in the carbs as I can for that first crank, and that seems to help. The problem is worse when the engine has been tilted up overnight, so I figured the gas was draining out of the carbs. I have no accurate way of guessing the hours on this engine, although it has been in the family since knew, I took it 4 years ago. I am guessing between beetween 1000-1300 hours. Still runs like a scalded dog.<br /><br />Good luck.
