Tune Up - 1976 15Hp Evinrude - w/Pic

[OptsyEagle]

I am doing an ignition tune up of my motor since it does not currently have spark in either cylinder and I have a few questions.

My kit came with 2 sets of points and 2 condensers. It also came with 2 small phillips screws and a black piece of felt material about 1 inch square. It also has a small capsule with some material inside. My questions are:

1) What are the two little screws for?
2) What is the felt material for?
3) What is the capsule material for?
4) How do I adjust my points to 0.020". In my picture (current old points) is screw #1 the adjusting screw or #2. And what do I do with them? I have a feeler guage.
5) Should I clean the new points from my kit or assume they are as clean as they can be since they are new?
6) Am I supposed to oil #3 in my picture.
7) I have a little rust on the taper part of my crankshaft. Should I do anything to try to remove it or just leave it alone?
8) Is there a way to test the primary coil since I will not be replacing it.

Sorry for all the questions. The flywheel was a real bear to get off and I am hoping to do it right before I put it back on. Any other tips you can give will be appreciated.

Read the following thread: http://forums.iboats.com/showthread.php?t=281957&highlight=adjusting+points

The felt pad is to apply lube to the cam. Replace with the new one in the kit. The capsule is to provide some grease for the felt pad. Only a small amount is needed.

Just taking a blind stab at this since I cant see the screws your asking about.
and I am in no way an expert. I would think the two screws are replacements for the screws that hold your wires to the points. The felt is for you to cut a new piece to replace #3 in your pic. Add a few drops of oil to this wiper after you put it on. The adjustment screws are NOT #2, those are for the spring in your points. Loosen slightly the screw that is marked #1
you do not want it very loose at all, then the slots you see at 1 O'Clock and 7O'Clock are for a large screwdriver to make the adjustments. Tighten #1 screws and recheck.

Hope this helps. and good luck.
Remember to find the torque value for the nut on your flywheel as it is for real a criticle torque. Too loose you will shear that little woodruf key, too tight you will ruin your crank.

Thanks for your replies.

So I should replace the wick #3 with the felt material from my kit and apply a light amount of grease to it, from my kit?

The screwdriver I use to adjust the points. Would it go in the slot that I have marked #4 on this picture?

Is it safe to assume the points from the kit are already clean and ready for use after they are gapped?

The point sets I got have new wicks with each set. Just one wick is used. If the felt you have is thinner or not the size of the wick it may be intended to clean the point contacts. The contacts need to be clean. No oil, finger prints ETC. Then once gapped they are ready.

It may just be the picture, but I see no screws in slot #4. These are special cam screws that you adjust the points with. Can't live without them.

Thanks for the replies.

Since a new driver coil does not come with the tune up kit, is it same to assume mine is OK or is there a test to confirm it?

Do I need to do anything to ensure proper timing or does setting the points at "set" and putting the flywheel on its key, pretty much do this? I will make sure the follower cam is set at the arrow for throttle timing.

Lastly I seem to have about 3 different suggestions for my 1 inch square felt material from my kit. One is to replace the wick (#3 in picture), the other is to use it to wipe the supplied grease on the crankshaft cam and the last one was to use it to clean my points once they are set. Anyone have any tie breaking thoughts or logic on this material.

You don't "clean" the points with anything. They are typically plated with tungsten, so they should not be cleaned, filed or messed with in any way. And keep your fingers off the contact area. Just install them and set the gap.

The felt is to replace the wiper for the cam, but doesn't have to be used if the old felt is OK.

The points have no bearing on the coil. It's either good or bad, but the points have nothing to do with the coil condition and nobody assumed anything.

Thanks Jim. With respect to the driver coil, I was just wondering if there was a test, perhaps with an ohm meter, to determine if it is functioning well. My motor is not putting out any spark on either cylinder, at the moment. I am hopeful the tune up with new points and condensers will prove helpful, but would be glad to test the driver coil if possible.

I have a 1971 18 HP that appears to have not been used a lot. I know it was not fired up in 20-25 years before last Thursday when it fired on the third pull. So the 39 year old points, condensors, and coils were still good. But for the price of new componants you purchase a lot of convidence. I ordered all new stuff. IIRC a coil is about $20 or so.

Heck, I was married in '77 which is a year younger than your motor and I have had my coils changed a couple times.

Just get a new one and worry less.
