Re: Help with an OLD Evinrude.
I've had 4 of those things.
1) Problems with the tiller handle on all of them. The plastic grip is brittle and crumbles away during use. If you try to steer with the tiller at any angle other than straight out, the casting will crack.
2) Crumbling seals in the carberator were constatly plugging the carberator up. Easy enough to replace. When you put the needles back in the carb, they're seated and then turned out to a 'neutral' setting. I think it's 3 1/2 turns on the low jet and 2 1/2 on the high? I can't remember.
3) Any cracking on the coils and they should be replaced. I never replaced any points though.
4) Great motor, easy to work on. Get a large screwdriver. A big one, like a 3/8 or something.
