MS 200T running problems - Again!!

[fen01]

Hi,

 

I have seen all the other threads relating the poor running (carbs) on MS200Ts and would like some advice from those have manage to fix their saws.

 

Mine starts without too many porblems but is really difficult to get it to rev out - it often cuts out as if it is not getting fuel or bogs down then dies. However, once i coax it up to max chat - useually by blipping the throttle it holds revs well and is not short of power, but once the throttle is release it tickes over for a few seconds and then dies. It has a new plug and air filtter and the fuel filtter looks pretty good. It a 2007 model and doesn't get that much use.

 

This happened 2 weeks ago and i assumed that the carb had gummed up and all was well after blowing some carb cleaner through the carb. But exactly the same occured again today after a 2 week break!!!

 

Sound familier to anyone? Any advice (I can't afford a new one)

 

Also where is carb model number on the carb- i have heard all the issues with the D types.

 

Thanks in advance.

Yep, sounds familier. Is the new carb any better? Or will i have to find a 020 carb?

same happend to mine went to local stihl dealer the said prop diaphram changed that still same thing happening so he stripped it right out and piston scored

Chainsawdom, did your saw have good compresion?

[chainsawdom]

yes still had good compresion mine started up ok but when you went to rev it it just went blur but if you reved it lighty a few times it reved up ok and when the revs are up and keep reving it it was ok

Was the repair expensive? And did you have any work done on the carb at all?

This carb model for reasons unknown has been plagued with problems .The usual malfunction is a crack that developes in the metering diaphragm side of the carb body .If that be the case there is no repair only replacement .

 

This is a picture of a faulty Zama carb from a Stihl MS 200 T which was sent to me from Australia several years ago .

I have found a 020 carb, i assume from what i've read on here that it will fitt straight on without any porblems. Is this true?

The carb will fit but you might have to blank off the hole in the black plastic carb cover, the square section you remove when you undone the 2 8mm nuts that hold the carb on.
