Just got this in the mail over the weekend from a fellow in Michigan. At first glance it seems rough, but that's just oil and sawdust and more oil and more sawdust. I've already had her running with a bit of fuel down the throat of the carby, but it won't idle or rev up without dying. Compression peaked at 158psi and the piston is a bit varnishy but otherwise clean. The only major thing wrong, so far, is one of the bar studs is stripped out but that can be fixed. The muffler has seen better days but it is solid so it will stay that way (Is that the right muffler for this saw?). The seem to be a bolt or plug or vent missing from the backside of the gearcase as oil ran out when I briefly had the saw running. Starter grip is a little funky. Sure seems like a mean saw, almost more so than my 3100G. Now the question is, the seller had a 990G also, not as nice but it has a roller nose bar instead of the hardnose 9/16" I have. I think I may have to give him a call and secure that saw. Chris B.      |

Chris...nice solid saw ! It seems we all need pulley covers for our old saws !

I guess they do turn up missing. Good news is the cover my 26LCS fits right on this saw so there is a lot of interchangeability.

I bet that cover fits my 4-20 and probably MCS's 20MCS as well. BTW, what does that pulley cover bolt to ??

I bet that cover fits my 4-20 and probably MCS's 20MCS as well. BTW, what does that pulley cover bolt to ?? If mine disappears I know who to go after!! Seriously, it doesn't bolt to anything, it just fits into the gap between the starter grip casting and the spring housing. I'll bet the same cover fits any Homey with a ball drive starter. I spent some time today on the saw. First, I fixed the stripped stud with a 3/8" x 2.5" bolt loctited through the case. It's probably the best I can do for now. I'd rather not helicoil unless I have to, and I shoudn't have problems so long as I don't let the bar get loose. I tackled the carby next with some new diaphragms, but it still wouldn't idle or even respond to adjustments. And if I tried to goose the throttle it would die. Changed the outer fuel line and it behaved the same. Looked at the inner line which appeared OK but fit very loosely on the nipple. Once I changed that hose, I was in business. Took a bit to readjust the carby as I had it all out of whack, but now it idles nicely, doesn't smoke, and revs beautifully. Definitely a very nice saw, has a wicked pop to the idle. I'll be setting aside some time to tear it completely down for cleaning. BTW, that 9/16" chain I have with the saw turns out to be full chisel. Hmmm. I wonder how it'll cut. Next project is keeping the rope on the recoil pulley. Keeps jumping off. I can't figure how it is supposed to be secured. Are there any owners or repair manuals out there for this saw? Here's a couple more pics. Chris B.   |

Chris....Chainsawlady has put an old 775G pulley cover in the mail to me so I won't have to steal yours :>)
I am interested in the light tan residue in the muffler on your saw. First time I have seen that on a 2 stroke. Possibly run with a lean oil mix at some point in the past ??
Does the pulley cover not keep the rope on the recoil ??

I should have acted faster and I might have ended up with that cover. Anywho, the cover wouldn't keep the rope on. At least, not with the knot I tied. As far as the tan residue, the muffler is pretty dry, but the piston doesn't show any evidence of seizing. Got a file ordered to sharpen this chain, need to dress the bar, a little more tweaking and this will be ready for work. Chris B. |

If you have an electric bench grinder you can dress either a 1/4" or 5/16" stone to conform to the 9/16 chain ;D Just use a 1/4" file. It should be fine. Maybe a bit more hook on the tooth but not that much. Why don't you convert it to 1/2" and get some chain from billg  |

I was really hoping you had found some 9/32 files  I have quite a few saws with 9/16 and 5/8 pitch chain on them. many of these chains are new or near new so I want to use the correct size to keep them sharp   |
