    Evenrude mystery

    My '72 Evinrude 50, 2 cyl w/ electronic ignition sometimes won't start when cold. It has no spark. Eventually, it gets spark and will fire. Once it does start, it runs great and will restart every time until it gets cold again, then may or may not start. I can't find anything wrong. I...

    1972 Evinrude 50

    I recently got a 1972 Evinrude Lark 50. In general, it runs very well. It has plenty of power at the top end and runs pretty well at lower rpms. The only problem is with idling. Even with a fast enough idle in neutral to make the gears clunk when engaged, it will slow and stall when put into...
