View Full Version : motor repair
I have a 1985 Evinrue 40 horse outboard that runs like a champ, when I get it started. Therein lies the problem. the motor is very hard to start initially. This is inconvenient at boat launches and docks. And embarressing! I've had it serviced and yet the problem still exists. after the initial startup I can stop and still fish and the motor starts up like new. Is this a carb problem or maybe a fuel malfuntion, or what. Help is appreciated.
SJ, that would be a pain,you may want to try different heat levels of plug? After you get it started your plug can fire the fuel, don't put
too hot a plug in though as it could cause piston
problems. Also, could be too strong a fuel mix.
Just a my 2 cents worth, hope you get it pegged.

One thing you might check is simply your fuel line squeeze bulb. Once I was having starting problems with an old Evinrude and it turned out I had a failed check valve in the fuel line.
Another thing to check is your primary compression-- not in the cylinder, but in the crankcase. The fuel pump runs on a diaphragm-operated pump cycled by the crankcase pressure; also the crankcase pressure is what forces fuel/air mixture into the cylinder. The service manual should have troubleshooting tips for that.
Yet another possibility-- check the linkage on your choke. Open up the motor cowling and (if equipped) remove the flash arrestor so you can make sure the choke is closed when you first try to start. I'm sure you've already tried all the variations on warm-up lever and choke combinations when starting; on one old motor, I had to have the warm-up lever down and the choke full on until the motor first caught, then quickly raise the warmup lever. Nobody else could ever start that motor.
Good luck! Nothing is more frustrating than sitting at the dock wishin' you were fishin'...
