Is or isn't?

Got my post backwards here. Message on bottom.

I'm not real sure if the Walbro was offered much past the number change from 020 to 200 .
Might have had something to do with the advent of the so called "intela carb " system .Hard to say where that idea came from .Could have been a Stihl inovation or perhaps EPA mandated .Then too perhaps different carbs where used in different parts of the world ????
Al, Stihl swung to the Zama carbs for the design of Zama's patented accelerator pump which they developed in the mid 1980s. When I worked for Stihl in 1989 they were contemplating this carb for their weed trimmers. Now as we all know the MS200 has used it .
Here's is a article from 1986.
BTW Jay you won't go wrong with that rear handle.

Willard.
 
The diagram does put things in a different light so to speak .Eddie had a good explaination but I just couldn't get it through my thick head how in the world that thing worked .
 
Thanks for posting that Willard. Makes it clearer to me also.

So is this the guy responsible for our Zama carb problems. Lets string him up and lynch him.:lol::lol:

Seriously, all this looks good on paper and the theory is good and sound but somewhere along the line it just doesn't seem to be working out as good as the engineers thought it would. Seems it has made more problems for Sthil and us lowly peons :lol: who use their products. They may have tested the pump accelerated carb in the lab for 100 of thousands of cycles but did anyone think to leave the carb sit around for a long time ,let the fuel mix evaporate from it and leave gas residue behind to make the pump stick or not seat down onto the carb body.

New and different doesn't always translate into better. Personally I would rather have a little less zip in favor of a reliable carb. My MS 200 rear handle just like the one in the auction succumbed to the same carb trouble that keeps getting posted here in the cahinsaw section:cry::cry:. You would swear the saw had a gigantic air leak but a carb switch from a T made it settle down and run much better. Like Al said though the carb from a rear handle 200 and a MS200 T are different in the way the Intel hooks up to the air filter. I had to jam the T carb into the air box to make it fit. This will do for now till I can get a new carb for the saw.

What does amaze me is how this these little carbs are manufactured with these parts installed in them. I have to give Zama credit for that one.
 
Well like I had said before hand after I did the red Loctite treatment I really haven't had that many problems .However due to the nature of the tiny race horse it might require a little tweak now and again .That I can live with .

In my preoccupation on this danged house I haven't fired a saw up in a couple months .It might be my luck the little pot lickers will give me fits when I do .

I worked at Kubota tractor in Southern California for a spell, a warehouse boy. It was a pretty neat job working out in the airy environment with a good buddy, no hassles at your own pace some distance from the office, packing and shipping parts to go all over the country, really a lot of fun. The engineers would sometimes show up from Japan. They were definitely in their own world. They had a seriously locked cage off in a corner for themselves, where they did whatever they did. I don't recall one of them ever talking to anybody who wasn't an engineer, it was a rather insular world that they seemed to live in. There was a definite sense of elitism that you got from them.

Oh my does it crank them up if you prove them wrong .I did that on a regular bassis on one job at Anna Ohio building a Honda auto engine plant with much delight I might add .:D Fact is I still do .I could care less if they are Japanese , American , French. If they are wrong, they are wrong .

An engineer who graduates from the most prestigious of them all, Tokyo university engineering department, is NEVER wrong...they think. You wouldn't believe what it takes to get into that place.

I won this 020 at the auction tonight, a bit over two hundred. Have to see about the oil pump not working.... I have a good 14" Stihl bar for it that has been kicking around my shop for quite some time. Eager for some bros I work with to try it out too. They don't know about them.

Thanks for the help about the model. :)

It could be something as simple as the plastic drive gear being broken or worn off. Remember that 98% of saw users end up using them dull which cooks the drive sprocket and driveshaft with a ton of extra heat. The little plastic oiler pump drive gear is often the first casualty.
 
I have no idea if the shipping cost would exceed the value of the item, but I would be willing to mail you an extra pump and/or drive gear off of a parts saw I have in the shop.
 
Shipping should be relatively cheap I would think .Example being I shipped a Mac carb to Mac Bob in Australia for 4 bucks via US air mail .

That's a great offer, Brian, much appreciated! I haven't seen a used pump being offered here anywhere, and don't know anyone with a parts saw. A new one would no doubt really cost, the way they get you here. I'll gladly cover the shipping.

I should get it this week I imagine, and after checking it out I will let you know.

Thanks very much....way cool!

Speaking of shipping, I heard a crazy thing today. No items over 500 grams in weight can be air mailed to the states now for security reasons. It has to go by surface. I guess it applies from everywhere. Have you guys heard that?
 
I might even have to rub some dirty grease on it so that customs doesn't give you such a hard time about 'declared value' or whatever. ;)

I consider grease my friend! Usually customs is pretty good about not collecting sales tax on anything under about a $100. Over that and not much gets by them. I think that there must be few countries that collect sales tax on imported merchandise. A scam or protectionism, either way you look at it. A couple years ago they suddenly started doing it, and appear to have studied well. :(
 
I have no idea how Japan views things shipped in as gifts .On that though I have shipped stuff into Canada listed as gifts because they in fact were . The last was 15 or so pounds of brand new carbide lathe tooling ,they never said a thing about it .

The gifts thing declaration doesn't seem to work on things that come this way. Sometimes writing 'USED' in ridiculously huge letters can help.

$27 seems about right. ;)
 
Congrats on winning. Looks good. I didn't think those rear handles were available for the older model 200's with the screw in gas and oil caps.
 
I am so darned compulsive I keep seeing this thread and keep wanting to respond with "It depends on what your definition of 'is' is." Its a really bad joke but now that I've posted it I can go on with my life.

Darin, this thread thanks to everyone, has taught me what "is" is. What I hoped for. :)
 
Frozen could mean a piece of sawdust stuck in it too. Sometimes running the pump backwards with your finger and some gas will spit out crud
