Re: CS 40 Issues **UPDATE**

Well, I replaced the crank seal today. The old one looked like new, and I shoulda just put it back in, but the new one was only 6 bucks shipping and all, so it's in there. I put a new piston ring in it while I had it apart(11 bucks with shipping). It runs about the same, maybe a touch more grunt. ???

I had our local Stihl dealer put a new kit in the carb a month or so ago. He charged me 13 bucks, and the kit came from ebay for 8 bucks. He also checked the compression for me and it was 140 psi. It feels a bit stronger now with the new ring.

I noticed today that after a few cuts it would idle rich, I'd piddle with the throttle to keep it running until I found a screwdriver, and all I'd have to do is just tap the "L" screw and the idle would change. Can the needles in the carbs just plain get worn out from too much adjustment? Or would that signify some crap in the carb?

Of all my working saws, this one is my favorite one. It's light, starts good, and cuts with an attitude like it thinks it's bigger than it really is(it's 40.2cc's)! I've got close to a hundred and fifty bucks into it now between the initial purchase price, new bar and chain, plus the  parts I've thrown at it.

Do I try to find a new carb for it, or just run it till it blows? Or have someone with a sonic cleaner clean this one and put it back together? Or maybe just admit defeat and mail it to uncle Al and have him look at it...for a nominal fee, of course!(I hear he works for beer ;D ;))

And... Is it common for these saws to NOT have a crankcase gasket? In the parts breakdown they show one, but this one didn't have one there. I just used a little bit of the transmission sealant that Case/IH recommends when I put it back together. :-\

Thanks for your patience gentlemen! :)
