Author Topic: Stihl 031 Coil (Read 1689 times)

I have an older (1984) Stihl 031 with a bad coil.
The shop I gave it told me the coil is bad. The points and condenser are still good.

Stihl supposedly discontinued the coil. Since it looks like it's impossible to get another one, does anyone know if I could use another coil from another saw?

Or, does anyone know the inductance of the coil that I'm supposed to have?
It is hard to believe that there is no other coil in the world that would work.
Even if I have to mount it differently than the original.

Cheers

Whats wrong with EBAY? There are 4 listed

Three are from a saw that had electronic ignition and mine has points.

Is there a difference? if any?

And the fourth one is a service to repair the old one.
Which seems a bit high.

The parts list shows two different coils and two different flywheels .If I'm not mistaken on that one you have to pull a plug on the flywheel to set the points .

Seldom however does a points type coil go bad .Usually what happens is the low voltage portion of the circuit encounters high resistance and it just fails because of same .Corrosion of some sort perhaps ?

Unfortunately I don't have the specs on that model but would suspect the points are set somewhere close to 18 thou .

Thanks Al
Looks like we may be neighbors. What part of N/W Ohio are you from?

I may have to run over to the shop so I can ask more ?'s.

Near Lima .No shop I just tinker .

So the shop is telling me the coil is indeed bad.

Does anyone know what I should read when I meter across the coil?

Also, is it simple to convert over to the electronic ignition and get rid of the points? This way I can purchase the coil?

Cheers
