Ms200t running rich

[desired_affect]

Im having a problem with my ms 200t its running rich at the moment but cuts very well through big bits of wood but when you turn it down it seems to loose all power.

Ive got it stripped down at the moment to put a new set of piston rings and crank seals in it, is there any thing else any one can think that i should do wile i have it stripped down or that will sort out the problem of it running rich???

could it be some thing to do with the carburetor????

 

and does any one have a parts list for the saw mine when when my external hard drive died

Buy a carb seal and diaphram kit and do the carb as well for what they cost

If it is still running rich after a carb kit then look at the air filter for restriction.The carb high and low speed mixture adjustment settings(screws) may require retuning.By the way,its not overly oily is it,as in too much two stroke oil? Somtimes the spark arrester guaze in the muffler carbons up as well,lol

have a look at the make and model no of the carb mate then ring stilh and see if its one of the dodgy carbs they had , if it is then they should send you a new carb for free !!!!

well its all back together and clean looks like new :biggrin:fitted with a new carb so hopefully tomorrow when i go to tune it up every thing will be fine.

*fingers crossed*

Just got this problem with my 200 it wont idle and as soon as you rev it it bogs down unless you gently rev it then it will reach full revs tried another carb no difference compression is fine no internal bore damage.

get the make and model no of the carb and phone Stihl ,ask to speak Greham and give him the carm model no and name he will tell you if the carb is one of the dodgy ones and if so they should replace it for free , i had exactly the same problem with 3 of my stihl ms200T'S

The little pipe from the cylinder to the carb (well attached to the handle) hasnt fell off or split has it?

 

Or could be the rubber intake manifold boot has a split in it.

got mine running a treat now, replaced the piston rings and crank seals, put another carb on and just cleaned up all the connections on the coil and it now runs as new.
