Hello, this is from a somewhat newbie to the experts. I have looked at the tune-up procedure on this website and it shows the guy using an ohm meter and test lead while the coils are off. My question, is their another way to get the timing and firing exactly right without this method. I just set the points on the high lobe of the cam. Is this really ok? It is a 1958 7.5h.p. evinrude. Just wanted some expert advice. My motors have always ran good, but didn't know if they could run any better.

Re: setting points

The easiest and best way is to use a timing fixture. F_R on this forum sells them, along with many other extremely useful tools for the DIY'er that wants to work on antique outboards.

Here is his website. I have all of his tools

Using a feeler gauge is used by a gazillion boaters and will get you running and on the water. However, it is not perfect. The deal with the timing fixure is you can get the cylinders to fire EXACTLY 180 degrees apart, at exactly the right time. Using a feeler gauge at 020 is just a means to get you close to this setting. But unless you are Spiderman, will never get it right on.

Re: setting points

That is one of the purposes of the timing fixture. It permits free access to the points to see what you are doing, and to adjust them. It also prevents the accidental movement of the shaft that usually occurs with the keep-removing-the-flywheel method. Yeah, the flywheel can be used as a timing fixture, but it is a pain and hardly worth it that way.
