What's on your bench today?

IMO the 200t runs as fast as it needs to for working with. A sharp chain will always cut quick enough.

 

As its been said the exhaust can be modded but I can't see much point. Wild you want a fast revving top handle in a tree???

 

Plus with all the problems a 200t comes with money would be spent fixing it rather than modding it.

Yeah what ever, I've been running modded 020ts for years with no problems, exhaust mod and polished inlet and outlet ports is all I bother with.

After doing similar with the 1st one, I have only done the exhaust mod. Best gains by far (& they sound fantastic )

Yup and I have read the thread that accompanied that vid and it is what I have found - the exhaust port can be widened but by not that much, the inlet port can barely be widened - if anyone disagrees then feel free to do so and snag the rings:001_rolleyes:

 

The squish can be lowered by around 0.4 - 0.5mm and the muffler can be modded that can make a decent difference.

 

Peter is right, don't know if he is repeating what I have found but it is fact.

 

The only thing I haven't tried is messing with the ignition timing.

 

not sure why but the american ms200 appears to have abit more zip from stock... are they running different carbs or mufflers?

I don't believe there are any differences!

 

Been putting a few new parts on one of the MS200Ts in at the mo, if your fast idle (warm starting position) doesn't work on your MS200T, the arrowed bit of your throttle is probably missing:blushing:

[TerryTibbs]

One of ours Steve? Tom or Harry?

Sorry, this one is called Ben and now has a new piston, a trick base gasket and runs nicely, just needs taching now!

[TerryTibbs]

Ah, the one at 185psi! Very good!

what does this entail

[spudulike]

Been working on an MS200 by the name of Harry, it always worries me when someone else has cleaned some parts and left others dirty:001_rolleyes:

 

I got down to the piston and it looks like a lump of carbon has damaged it - probably still workeable.

 

The main problem is with the colour of the crankcase transfer cutouts, these were brown and not the normal white colour, one of the arrows points toward the crankcase gasket that hasn't been trimmed when the cases have been apart - probably would cause an air leak etc:001_rolleyes:

 

The crank bearings have been replaced and have either been put in the wrong way or just not been pushed fully in to place causing the crank to be tight and overheat in use when the crankshaft has been binding against the bearing. Not good!
