MS 200t with no power

Lookinup

Lookinup

I am trying figure out why 2 of our MS 200t's have no power. They aren't hitting the top end and fade immediately in a cut. I have done the spark plug, air filter. I also removed one of the carbs and inspected it but found no particulate inside. I haven't tried the fuel pickup yet, but I don't think its the problem because one of the saws is only 5 months old. Any thoughts?
 
That would be my vote as well. The spark screens always plug up. Remove the spark screen and screw, turn the H jet out more by 1/4 of a turn, and presto you just gained gobs of power!

Good Luck

Have you removed the spark arrestor from the exhaust port?

Almost for certain that's it. Easy fix but you may need to adjust the carb a bit.
 
My 200 would run and fade in the cut occasionally. There was a crack in the fuel line. Replaced it and good as new.
 
There was a problem with the original fuel line getting poked by anything from sand burr thorns to general pointy sharp things...bleeding air into the carb. One fix and never again but if you don't smell fresh fuel while climbing or messing around, that's probably not the problem. Again, the arrestor screen being nixed does wonders.

Wanna know what kind of nightmares I've had lately?

I'm way up, start the saw...and the fuel ignites. That would indeed make for a crummy day.
 
That fixed the crap out of the newer saw. The older of the 3 that are hurtin are still no power. Good plugs, winter setting is on. I think I should make sure the carbs are at factory settings. Where is a good source for that? Does anyone know where I can get stihl parts breakdown sheets for some other saws?
 
The best source I've found believe it or not is Ebay....type in Stihl MS200T and most of the responses are manuals and parts lists. It sounds like if your older 020's are stihl slow it MIGHT be carbon build-up inside the muffler from trying to push thru the screen all this time. Have you thought about porting thru from the bottom with a 3/8th's drill bit (simple and crude quick-fix)?
 
With the older ones I would start with checking the hoses, impulse/fuel/tank vent, then check that all the heads bolts are tight, check the intake boot, rebuild the carb and pressure test it. if it has the older styloe Zama they are notorious for cracking throgh the venturi and cracking around the fuel pump. if this is the case you need a new carb. Ill grab the latest and greatest Zama part # for you later if you need it.

Stihl parts blowups are hard to come by, Stihl generally serves cease and dissist orders to anyone on the net that publishes them rather quickly. you could go down to your local dealer, tell him what your after, and he MAY print out what you need.


good luck!
 
...and it always helps to give the boys at the dealership some consideration of gratitude around the holidays! Home-made jerky, pickled jalapeno peppers, whiskey, or even dancing girls at their Xmass party, all wrapped-up nice and pretty.
 
I had 2 200s and a 460 loose alot of power all at the same time last year... Turned out someone forgot to mix the gas. We usually use the oil with blue dye in it but confusion started on the previous batch when we mixed oil purchaced from a gas station because we didnt have any on the truck. Did you check the compression on those saws. my 200s still ran but really crappy. They are now on my parts shelf

I'm not sure if running over a 200T with the chip truck is as bad as fueling-up w/ straight fuel someone forgot to mix but either way, it's enough to make a hardened man cry.

I feel for your loss. 200's and the 460 are indeed crew members with souls and tools that deserve a mention at the Thanksgiving table alongside the best of our loved ones both passed and present.

How many of you felt like your eighth Christmas morning when your wish of a B-B-Gun came true and you couldn't sleep that night thinking about all the big game and target range possibilities the next day? That's me when I leave the dealer with a new Stihl. I bring her into the house, set her on the kitchen butcher block and admire her for the beauty and presense of her being. The first week I reluctantly bring her to work, guard her with my all, and make certain no chip or oil spill or yuck pollutes her shine. No one can touch her, only lavish praise on me for my expensive investment in something of such greatness. Eventually someone asks "Where's the 460?" I ignore them in hopes they'll grab for something else. After two weeks, they just take her but I watch from above, carefully, and shouting threats of murder if they mess her up and completely unable to concentrate because I'm listening and aware, my hundred-fifty percent attention turned to the possible slob and irresponsible thug that's molesting my baby. He's aware too, of my attention, which makes for a very inefficient day. Irregardless, all seems to go smooth.

Then we rake it up clean, submit the bill and pile in, across town to pig-out and celebrate and when coming out of the diner with fat bellies and chewin' our picks...the 460 is gone. Friendships suffer, comraderie challenged, ugly words and possible fisticuffs ignite. Kill these jerks, wish 'em dead, fire their lazy arses.

After a few minutes I wish now I could go back and fix, I realized I stashed the saw under my truck in the hopes of prolonging her life from multiple users, keeping her from grabbing distance to chop down brush and crud while other more adaptable saws were at more disposability...and my baby is left in an alley of a location of questionable refute, flattened beyond repair to the point that wandering youthful gangsters didn't even want to procure.

As hard as loosing my Dachshund last year, but that wasn't my fault.
 
I have been reading were some of the Zama carbs on the 200T came flawed from the factory with a crack inside that is creating carb problems as described also. So after checking a plugged screen. Try a carb for a 200T that you know is good and dont bog in the cut.
Only fix is a new carb. The crack is so small you have to use a magnifying glass to see it under the diaphragm area.
