my Stihl 031

[DanS]

I picked up an 031 that wouldn't start. The previous owner claimed it was the carb. The carb was fine, it was a spark issue. I replaced the condensor with a WIMA capacitor (thanks to a search on this site), and now i have a great condition stihl 031. I love these saws.

Holy crap......that is one nice looking saw.

thanks dano. im pretty happy with it
it's done bugger all work. compression is awesome.

Nice work. I have had success with this repair as well. Excellent spark at low rpm. I'd be interested to see pictures of your capacitor placement.

i'll take some pics if i take it apart again. i just put it where the old capacitor was. i had to grind away a couple of tabs in the case with a dremel. then i pushed the WIMA capacitor in there (held in tight by the case), and put some silicon underneath. the capacitor electrodes were facing outwards.

Mine went in the same location.

guys, this repair comes up often, is there a thread that explains/details it best ?

The link to my thread is in there as well (sans photos ). I plan to do another with pics when the weather warms. Thanks to flyboy for this repair, I wish he was around here more often.

Dan, I found a picture from mine. I also fashioned a retainer for the capacitor.

That warms my heart. I reverse engineered / came up with the wima fix around 7 years ago. My 031 still runs with it.

that retainer is a great idea. if mine ever comes loose, i'll do the same. i have 9 other capacitors if this one gets destroyed

I've got one of these lying around, waiting for some TLC. Good to see someone still getting good use from them.

That is a very nice looking saw. Still have my dads, it is what I started cutting firewood with. They might be a little heavy by today's standards, but a pleasure to run.

I parked my 031 because I was having a lot of trouble getting it to start after it was warm. Started fine when it was cold, do you guys think the condenser may be my problem also?

That would be my guess. Heat affects them at first, resulting in poor, intermittent spark. Which makes them run rough hot at first, before eventually failing. The beauty of this fix is that it will only cost you a dollar or two to try

Hard to tell, but most likely if your fuel delivery is proper. Set up correctly this repair will make an 031 fire up half way through a slow-ish pull.
