Re: 70 hp evinrude.....wondering?
Howdy MBooher.<br /><br />Steelspike is right, fuel problems can cause that, but more often it is because the engine is running on only one or two cylinders.<br /><br />Short out each plug with the engine at idle. If a plug doesn't cause a drop in rpm that cylinder is dead.<br /><br />Check for spark on any dead cylinders.<br /><br />Got a dead one with good spark? Squirt a bit of fuel into the carb for that cylinder and see what happens.<br /><br />All cylinders making power at idle? Go to Steelspike's advice.<br /><br />Let us know what you find.
