Mikehonda, caught a notification for your reply in my email this morning. I appreciate your replies. As you can see, my last reply was back in September. It starts getting too dang cold to be outside puttsing (for me, anyway) with a bull headed saw. I put it away til spring. As I stated earlier, I did find a carb kit, I just haven't installed it yet. I also bought a new plug and will be putting that in.
   I never thought about the switch being dirty. As stated earlier, once it's running, it runs great. Will just spraying it with contact cleaner do the trick?
   As far as fuel selection goes, the highest Octane readily available is 91 or 92. This is the only grade available, short of racing fuel without Ethanol in our area. I have already opted to using this in my other small engines (lawn mowers, snow blower, etc.) I will be doing the same with the saw.
  One other question with you being a new response on this thread, what is your input on my pull cord issue? As you probably know, the casing is molded plastic and the cord wrap is aluminum. There is no noticeable wear on either so I don't feel this is the issue. Is there anything, you feel would work to stop the cord and recoil from binding?
If we can't fix it, IT ain't broke!

Those damned starters can be as fickle as a teenaged prom queen.Don't oil them because all that does is attract little wood chips causing all kinds of problems.

Take the whole thing apart and make certain all the crud is blown out . What often is the problem is the tension on the bolt holding the starter drum in place .If it is too loose or too tight it will cause issues.You want just about one wrap of the drum passed full cord retraction on the take up spring .

Al, I hear ya on "being fickle" .... I took it all apart last time it bound up ... blew everything out, wiped everything down, including the spring, and put it all back together, only to have it bind up with the cord dangling all the way out again after ten or fifteen pulls. Is there a torque spec for that drum bolt? I tried not going too tight cause it's going into plastic but, I know it's snugged up. As far as lubing it goes, I figured oil would just attract dirt. Could I maybe spray it down with Silicone spray and let it air dry? I am about ready to find a different recoil assembly!

It's been a long time since I had one apart .It seems to me it's nothing more than a carriage type bolt and either a flat washer or a spring washer and a nut which I think is a nylock type .

It could be the spring itself getting wound up all over like a coiled snake .

Find you a friendly saw shop with a big "dead pile" usually a non runner will be cheaper than buying the parts to fix one with problems.

I hope this stays in this thread ... I failed to post in the spring ... my bad ... I did get the carb rebuilt. Put it back together, gaped and put the new plug in, put new gas in, ... 4 or 5 pulls, it pops, push the choke in, one or two pulls and she's running ... every time !!! Now, I just wish I could master keeping the chain sharp! lol ...
Oh, and as far as the issues with the recoil go, haven't had any. This may have been due to me pulling too fast and the recoil not keeping up ??

That series was pretty dependable if kept in tune .One note is periodically check for bolt tightness because given enough time they will rattle the bolts loose .It's all metric sized .

For no more than they bring on the used saw market it's a lot of saw for little money .A little heavy for their size maybe but still in all a good firewooder .The only reason my three are shelf queens is because I have better saws in my stable .A lot of plastic parts in them but they are still tough as a nail .I've seen them run for years with engine damage that would have killed the average saw engine .

the choke plate must lay tight to the carb body on these or your gonna pull your brains out. however probably the longest lasting chainsaw in the world if not one of them.
