Chainsaw Repair

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!

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!

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.

It may just be easier to drive up there and "fix" that turd!!!!!!!!!!!

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
