I've been trying to get an 038 Mag up and running for a couple of weeks now. I ran into a problem tonight, and I need some help deciding if this thing is worth fixing or not.
Up until now it's been mostly cleaning, adjusting the carb, new starter rope and such. There were concerns early on about some marks on the piston and jug, but that's been resolved. Had a bunch of junk in the bottom of the carb that kept it from running on the low end, but that cleaned up okay and now it's ideling pretty good. Well, I got it running half way decent yesterday, but the starter rope didn't want to stay in. I pulled the cover off, and put another turn or two on the coil spring, but it didn't help. Started the saw again this evening, and broke the brand new starter rope. I had splurged and bought one of the elasto-start handles for it, and man was that rope skiny. I wasn't sure why that happened, so I looked everything over when I pulled the cover back off. I didn't notice anything screeming "Hey, look here, I'm brokend!!!" so I tied another knot in the rope, and put it all back together. It was cold mind you, and I wanted to get my gloves back on. Well, started the saw, and backed the idle speed down a little too far and the saw died. Bumped the idle speed back up half a turn, and gave the pull rope, and it came out in my hand. Broken again. So I brought everything back inside and started tearing it all down. Pulled the cover off and found that this time the Pawl had busted in half. That was odd, because it didn't look too bad before. I looked at the pully that holds the starter rope and noticed that it had some wear on teh inside like maybe the washer was missing (but it wasn't). The pully has a lip on the outside, and the inner radius of that lip had quite a bit of wear on it. It looks like the fly wheel has been rubbing on the pully and that's why the rope doesn't stay in.
At this point I started looking real hard at the fly wheel. It is missing one fin, and a small part of another, and it looks like its been that way for a long time. The outer radius of the fly wheel looks pretty rough. One corner of the ignition module has been bent where the fly wheel came in contact with it at some point. I started turning the fly wheel over by hand, and noticed that it has a fair amount of play in it. At this point I started to feel sick to my stomach, and wanted to hurt something real bad.... I pulled the sprocket off and put a wrench on both sides so that I could get the nut off the fly wheel. At this point the nut is off, but the fly wheel is stuck on the crank shaft, and I'm letting some penetraiting oil (PB Blaster) soak in. Maybe I can get it off there tomorrow some time. There's no play in the side of the crankshaft with the sprocket, but the side with the fly wheel looks to have what I would consider to be a fair amount (maybe 1/32").
At this point I'm thinking that the bearing behind the fly wheel is worn out. If so, is this worth replacing or should I consider the saw junk? Is there anything else that could be causing this?
Thanks,
Mark
