I have a 1960 75hp Evinrude. Hasn't been started in a couple years. I've replaced all fuel lines, plugs and wires, cleaned out the powerpack which had some minor rust/dirt inside, new gas (24/1 ratio), inspected and cleaned fuel pump and replaced filter. I removed lower unit and replaced the impellar, lower unit gasket/seal and change the lower unit oil. I had the starter rebuilt also (armature was fried). Problem 1: When I try to start the motor from the switch the starter engages but can't turn the flywheel. Possible short from the switch to the starter I'm assuming? Problem 2: When I try to pull start the motor every couple of pulls or so I get some backfire but thats about all I get. When I pull the plugs out to take a look at them they are clean and don't smell a bit like gas. Could I have powerpack problems or stator problems? And if so how do I check this? A manual is in the mail and I'm trying to do some things before it gets here. Any tips would be greatly appreciated, thanks.

Hi,<br />Check the flywheel key to see if it has slipped and if not I would suspect the powerpack. They are hard to test and expensive to buy.

Hi nicnbj <br /><br />I dont see anywhere you rebuild the carbs. I' d suggest you do, as they usually get dirty when sitting for some time. If you get it started they will produce a lean condition that will destroy your motor when up and running. Try to squirt a good amount of premixed gas in carb intakes and pullstart. if it starts and runs for a couple of seconds, you got it. Good luck.

Agree with the carb rebuild.<br /><br />YOur engine doesn't have a powerpack. It is a point system. <br /><br />It is a good idea to pull the flywheel and check the points and pay special attention to the flywheel key.<br /><br />Also, are your plug wires connected correctly?

Plug wires are connected properly and are brand new. I will check the points, flywheel key and go through the carb. Thanks! :D

Points are in the magneto, where the wires come out. Under the metal plate below the pulley...just a Thought
