Stihl ms200t rebuild bolt for bolt vids

[Mattyo]

well, I'm workin on the vids for a couple 200t's I have in the basement. figured I'd do a full teardown and rebuild. never worked on these guys before, so please be gentle.

on thing I noticed right off was the timing numbers stock at 99 135 78 ... seems to me like the blowdown is too long. anyone have any issue if I knock that back to say....120?

I don't think i'll port the intake or exhaust... I may just leave those alone, but something tells me that blowdown has got to get adjusted.

i'm gonna mill .015 off the case itself to put the squish to .020... stock its .035. figure that should give them a little extra pop



anyway, here it is in case anyone missed the thread over at AS...

Any chance of selling ?

 

[Mattyo]

likely not... this guy is pretty attached ... and once I get done w/ buying all the parts I need...they ain't gonna be cheap

 

[skippy]

I may want one

 

[Mattyo]

I know other guys w/ these saws... maybe I can find one or two to rebuild ...

my main question right now is should I adjust the blowdown.. seems like too much...

Nice thread sir.

 

[jake wells]

these are easier to tear down than T540 husqvarna.

 

[Mattyo]

Just because I can take it apart...doesn't mean I can put it back together....or get it running lol!

Just the same....thanks! And sorry for the boredom that IS me talking hehe...

 

[Mattyo]

Likely so jake....haven't torn down a 540 yet...don't intend to

 

[jake wells]

* TIP * make sure the bar oil is drained from the tank before splitting case it makes the job less interesting

 

[Mattyo]

good tip.... it was mostly gone hehe

I heard the husqvarna 549 is the copy of the ms 200t . I don't know if this is the truth anybody

i have torn down two t540 and truthfully they reassemble each other but are different in nature the t540 is bigger pain to tear down because everything is crammed together.
specs t540 37.7cc, 2.4 hp, maxpower 10,200, 8.5lbs////// ms200t 35.2cc, 2.1hp, maxpower 10,000, 7.9lbs.

I love your Videos Matty.

Get that gasket yet?

 

[Mattyo]

sorry, I forgot to mention, yes I did.. Thanks!

 

[Mattyo]

Nice thread sir.

Randy, if you can answer this question for me that'd be great... it seems like too long of a blowdown... exhaust is 99 and transfers are 135 .. when I look inside the chamber the transfers don't have very much cross sectional area of opening. I really think I should adjust these down.... assuming I increase compression by trimming the case... what do you think?

Great video!! One question how in the world can you work on a 1x6 board for a work bench? If that would have been me everything would have been in the floor many times before I got done lol!!

On the 200T I just raise the mains. I leave the secondaries untouched.

I'll see if I have notes.
