200t

Ok, I have just referb my old 200t total strip down and rebuild . The reason for this is it has developed a running fault, runs lumpy until you blip the throttle then at full revs runs fine come off the throttle and it bogs down, few more revs then its ok again. I found the crank case seals leaking so replaced these , the local stihl supplier set up the carb and it ran sweet every time I used it until it sat unused for about 2weeks. Yep started first time then same fault. It seems to get better after it has been running for about 20 mins ??

Can any one has any one had a similar fault ,or can some one suggest anything.

Thanks for reading .

Impulse line come off ? accelerator ( piston ) pump knackerd ?

No checked the impulse line and getting good compression even changed the fuel cap o ring ....

Did not mean the piston of the engine . There is a small piston in the carb that acts as an accelerator pump when you first squeeze the throttle . If this plays up it can cause erratic running symptoms . You can mod it to do away with this with an earlier type of carb that did not have this feature .

Thanks Stubby I will have a look into this

No worries . Hope you get it resolved whatever it is . .

Yeah so do I , iv spent all day rebuilding it to still have the same fault.. iv got the new 201 and yes its a good saw but well you know the 200 is just great !

I don' get in trees any more as I'm 64 ! . I have a modded Husqvarna T540 ( its a Mk 1 but has the Mk 2 mods to it and that is a flyer . If your 201 is not the latest cm you can get the Stihl " enhancement " kit ( new fly wheel , ignition module and other stuff ) for about £ 60 . This helps a great deal . Good luck with the ms200 . They are a dying breed !

Don't suppose the carbs are inter-changeable between the 201 and 200 are they? Would be good to swap a known good carb on to the 200 ....
