I have an '86 Evinrude 70 hp. Engine cranks fine but will not stay running, unless i keep choking it. Any help will be appreciated. Thank you.

Re: motor cranks then quits

Hmmmmmm...... Sounds sort of like a fuel starvation problem. Maybe if it would stay running if you pumped the primer bulb, that might lead you to look towards the fuel pump, fuel line connections, primer bulb, fuel filter, gas tank, or the gas itself.<br /><br />Then again if that didn't help I'd think you might have to start looking at the carburators, or perhaps an ignition problem. <br /><br /><br />Of course there is always the possability that it could have an internal mechanical problem. <br /><br />Might try a quick compression check to make sure the compression is up to snuff.<br /><br />Then last but not least, broken reeds or crank seals could cause a person to have to constantly choke the motor to keep it running poorly.
