Mark3885, wire got here today, thank you so much. I can now get this little saw off my bench and outta here!

Hey Mark, it would have taken less time to drive to Rochester than it did to stick all those stamps on the envelope ;D! Seriously if you happen to be in Rochester, you should stop by the shop to bullchit for a while and suck down a couple of beers!

While repairing this saw I noticed that the tank vent was rotted completely off the breather pipe. Looked up the part from Stihl, just a tube with what appears to be two expanded bronze plugs in it, similar to something I saw used on some model of Poulan. Was about to order it when I realized Stihl wants 18$ for a two inch piece of tubing! WTF! They are nuts! Going to look round and see if I can find out which Poulan that setup was used on, or make my own using two set screws and a scrap piece of tube!

Yeah, make your own.  Just get the correct piece of tygon, get setscrews that push in a tad snug, but not too snug, and you don't want to thread them in.

Thanks Fish, I really appreciate it! I want this little bugger outta here, tired of messing with it! Given the level of use/mis-use on the saw I doubt that it was running when it got here. The thing has been rode hard and put away wet!

sorry, I must have missed the earlier threads on this saw.

Why would not a simple electronic ignition swap worked on this saw?

The saw uses the early SEM electronic ignition. That SEM coil has the ground wire permanently attached, it appears to be molded in the coil so no apparent way to switch the ground wire, at least none that I could discover. The wire was broken within only about a inch remaining attached to the coil.

Swapping out the coil would have worked, I'm sure however I did not know nor could I figure out what coil would work in place of the SEM coil using what I assume is a SEM version of the flywheel. Please, if you know what coil will work in place of the SEM let me know. The owner also had a budget within which he wanted me to work. A used SEM coil runs $60-80, which would have put him beyond his repair cost budget. So the only option I could work out was to splice a new section of wire to the remaining piece attached to the coil.

I have attached three photos of the coil I found on eBay.

Would not want anyone to have to drive to fix my problem! Is there something I could do to make a better fix? And 'turd' is correct! Stihls are not my long suit so any opportunity to learn something is always appreciated!

I found a reference to this in another thread, it appears to also be a SEM, will it work in place of the one on the saw currently?

Also found this, says it works but who knows:

Those ones you are looking at are cheap Chinese aftermarket coils, surely you have a burned up old 029/ms290 around, just slap that coil on and go cut some wood.

I have a couple left myself, off of a new ms290
