    Someone gave me a Husky 372 saying if I could fix it I could have it. Problem being the magneto wires tangled in flywheel vanes and got ripped out. The black shroud for air flow control shows three wire guides. Which wire goes where? Anybody who can help me?
    I am not familiar with this brand to work on.
    Its fire wood cutting time and I really need a real saw, not a tinker toy like a Poulan. Already wore one out. Chain, guide bar, and what have you worn out in 1 season. Cut 10 cords last week, need to do same next week

    Little black wire goes in bottom groove, it is the ground wire. Attach to ground at coil, and to kill switch. Little blue wire goes in middle groove, attach to kill switch and terminal on coil. Big black wire is spark plug lead. It goes in the large groove on top. If I need to tell you where to attach this one, you probably shouldn't be working on a saw.

    If you have to put the wires back together or add on to make them longer to reach,,do not twist together or tape..strip and tin and solder and use heat shrink tubing available at radio shack and many other places to cover the joints..if you do not know what this involves seek the help of someone that does..bad wire connections will kill you in the long term..

    Thanks! The HT lead I know. The other two wires got ripped from the tags on copil so no colors visible. Actual wires are missing. The guy who gave me the saw is notorious for being an inept tinker. I suspect this is how the wires got loose in the first place. Looks like further dismantling is required. Will see if I can somehow get a picture to post.

    For the very few dollars it will cost, I would just go and order the correct wires for it. You know they will be the right length, and have the proper connectors. Alternately, you may find a parts saw at a dealer.

    No Idea. Saws are older so not likely. The situation is this. I'm reasonably handy mechanically. Have always rebuilt my own four cycle motors and diesel trucks. Now that we have moved to the outback we heat with wood and suddenly the predominant motor repairs are for small chainsaws. Very little resemblance to 2 cycle lawn mowers or outboards. Paying work is scarce, so we are not only cutting our own fire wood but are supplying (paid) fire wood to seniors that are unable to help themselves. One guy has a number of 'dead' saws around and said I could have one if I could fix it. Best candidate is the one with missing wires. The other dead saws need pistons or carburetors which in turn cost $$$. Wires I can fix no cost. That's my business as a marine electrician / electrical designer. But I must confess I have not seen a two part magneto system before. The one with HT leads I understand but the other black module is ???

    It may seem stupid but have you hooked the HV wire to a plug and see if you have spark ??
    if you do the rest is to just ground the coil thru the on/off switch to shut it off..
    just for grins try it and see,,..i'm sure you could figure out the rest..

    Where is the other black module you are mention located? It sounds like it may be a heated handle saw.

    I do not have heated handles on mine but I think that is what is going on. The other black box is under the flywheel? are there wires running to the handles and behind the carb? If you were to hook up the single wire from the coil to the switch, and switch to ground, I think you'll be running.

    Great pictures. The saw I am dealing with is much older so module is black. And the wires are totally gone. Ripped right off the coil. Including the part that went to kill switch. I may have to dig into the plastic to extract a bit of tab so I can spot weld something onto it. Hopefully all the damage is mechanical and the actual coil windings are intact.
    Someone obviously had it apart at one point and got careless replacing things. He said "It started fine and ran for a bit then quit" Uh huh!

    From other things I have learned he is not much of a mechanics but talks a good line. I suspect he was responsible for buggering up the saw but won't admit it. He did help me cut fire wood and his Husky cut same size logs in half the time as my dinky-toy Poulan the brother in law sold me for a low price. Now I know why. His comment was toss away that da** thing and get a real chainsaw. Later he offered me this saw if I could fix it.

    Pioneer / Poulan ???

    I found an old saw ( fre) at a garage sale. The engine covers has both the name Poulan and a riveted ID tag saying Pioneer. Did Poulan buy out Pioner or did Pioneer house brand for Poulan at one time? Saw is clean but somebody allowed water to accumulate in the crankcase. Bearings are shot.
    After putting the whole thing through the parts washer and dismantling the whole thing I am wondering if this is worth while fixing or is it just a useless antique. Looks to be a 5 HP motor driving a 24 inch bar and chain.
    Piston looks good, no grooves or scoring and no corrosion. Just rust on the bearings.
    I love tinkering with old stuff and can't resist a restoration job. Now that we have moved into the back country from the coast, its chainsaws and tractors instead of boats I find lying around. .

    Dang Mike, is that 2171 new? If not, thats the cleanest used saw I think Ive ever seen. The Jreds are growin on me.

    Elnav, Im sure these guys will point you in the right direction, and you will be cuttin with the 372 in notime

    You need to come up with a model number for the Pioneer/Poulan.Then post your question in the Pioneer thread and in the Poulan thread.The guys that monitor those threads can help you decide where you need to go with the saw.If it's running a 24" bar,you probably have something worth re-building.
