I forgot about magnetos (I must be dain bramaged!). I don't know much about those. And I agree--Get the manual.
.
Assuming a distributor, the points are up under the distributor cap and up under the rotor. But you may want to just do a thorough tune up to be sure the distributor system is up to snuff.
.
Get the manual, a feeler guage to set the points, a cap, rotor, points, condensor and spray contact cleaner, too. To be thorough, get a set of plugs, a sparkplug guage and plug wires. A bad coil wire was something I forgot to mention. That'll stop you dead, too.
.
1) Unsnap the cap from the distributor. Don't undo the spark plug and coil wires just yet.
.
2) Pull off the rotor and throw it away.
The points and condensor (capacitor) are under the rotor.
.
3) Thoroughly clean out the inside of the distributor with the spray stuff. If it is particularly gunky, an old toothbrush helps, but expect it to melt a bit in the spray stuff. Let it dry out well.
.
4) Follow the manual instructions for replacing and setting the points. Don't forget to lube the cam with a little grease! Don't use too much, or you will gunk up the inside of the distributor.
.
5) Just unscrew and replace the condensor.
.
6) Press on the new rotor.
.
7) Put the new cap on the distributor.
.
8) One at a time, replace the plug wires, making sure that the position on the old cap for the old wire is the same as the position on the new cap for the new wire for that particular spark plug. It's easier done than said.
.
9) With the new plug wires in place, verify the firing order. #1 cylinder is at the front.
.
(Could someone remind me, I'm dain bramaged. What is the firing order for a VA/VAC, and is it clockwise or counter-clockwise rotation? I'm thinking clockwise, but... The manual will tell you.)
.
10) Gap each sparkplug to factory specs. Do not rely on them being gapped right. A bump or two in shipping and the plug gap won't be right.
.
11) Replace the plugs one at a time, making sure that the firing order remains right.
.
12) Fill the grease cup on the distributor (that's the twisty looking thing on the side of the housing), and then give her a twist or two to be sure the shaft is lubed. If you can find it, long-fiber low-speed grease is great for this.
.
If this does not solve the problem, it will certainly help your machine run better when you do get her running.
.
THANK YOU, by the way, for letting me help someone on this site. I owe this online team so much, I like very much to replay the favors I owe.
