Is or isn't?

I fixed it today. On the 020 rear handle...maybe the 200 as well, the ground wire attaches at the front part of the handle where the anti-vibe mount is located. You have to take off the carb and remove the handle for access. The coil kill wire also gets a junction with a connector there as well, the other end going to the switch end with the brass thing on it. The male connector tab on the kill wire was hanging by a thread, almost completely broken off, so when I turned the saw downward it made better contact to shut it off. With a better connection there it works fine now. Thanks for the help, and Mike was right about a continuity test being the way to go, but I don't have a circuit checker. Back in bizz anyway.

Typical .The fix took two minutes but it took two days to find it .Traveled that road many a day .

Typical for sure Al. Patience is a virtue in the world of trouble shooting.

--and on that patience thing I learned a long time ago if it gets to you ,walk away .Sometimes you get your cool back in a few minutes .Once I had an 042 that pissed me off so bad I banished it to the shelf for a year and half as punishment .--now isn't that childish ---:roll:

I have to walk away from mechanical problems too. A bad attitude just makes more problems.

 

[Al Smith]

Well you can't beat it into submission but at times I wish you could .

I've got a 192t that's been sitting on the shelf for over two years now, I'm still not ready to look at it again! I understand Al!

 

[Burnham]

Well of course, Andy. It's a 192. I don't want to look at one band new on the shelf in the saw shop, let alone busted on my shelf at home.

I've picked up a couple more 020s, people see the one I acquired and ask me to look for one for them at the auctions. I go through the saw, clean it up and check it out, make adjustments, and charge them a hundred bucks or so. So far I've had luck with the arrangement, all good runners that just needed a little attention. One thing I've noticed, is that they all have the tendency to burp when starting, do that thing where they briefly fire and snap the rope out of your hand. Wonder what causes that...maybe it's the Zama carb on there? Sometimes they do it twice before actually starting, seems pretty unusual. These are all early models before the new engineered carbs with the associated problems.. Do you guys find that starting tendency with the MS200?

 

[SkwerI]

It's probably due to advanced engine timing, these are as close to a ported saw as you will find in stock form. The early models also had a problem with blowback from the carb soaking the air filter with fuel. That's why they have that piece of foam below the carb inlet now, to catch the fuel drips.

 

[woodworkingboy]

The timing, that would seem a distinct possibility, good thinking!

I haven't noticed any wetness around the filter, but I also haven't looked for it. The rear handle models are a somewhat different arrangement from the top handles, use a different filter, I think a less space thing. That is the only difference I can determine engine wise, including the current models, except for the carb. I think the muffler is slightly different on the older versions as well, a bit more opened up at the exit.

Thanks again for the oil pump, Brian.

It's cool at the auctions, people are hot to trot when the 200s show up, but don't realize that the 020 is the same saw.

 

[SkwerI]

Glad you got it working so easily, Jay. And since it was such a small part, postage was only about a buck and a half. Pocket change.

 

[woodworkingboy]

Quick shipping for so cheap. I'd probably have to pay four times that amount going in the opposite direction. US postal rates are low.

Does anybody running a MS200, or it's forerunner, the 020, ever start getting a popping sound from the combustion while the saw is idling? It is like the saw is loading up and that sound disappears when you clear it out. Could be a carb thing on my 020, but I also notice it on another 020. Sometimes it takes a bit before pinching the throttle clears it out, or whatever happens, and the revs will climb normal like. It might be something particular to the old Zama carbs on the 020. I can't tune it out, just crops up, and possibly more so when the engine is hot.
Thanks.
