Stihl MS200t problems

[mdaalmeijer]

Hello,
First of all, hello there my american fellow arborists, here an european college!

So the new climbers saw called ms200t over here is the new model of the old 020. Me and menny of my colleges have been having the acceleration problems from idel to full, motor stalls.
So me and other guys over here have been looking for help at dealers ect. but as it seems no one can fix the problem. This weekend i was at the european championships over here in france. And thought to ask the stihl represetetive there what to do? The guy told my it has all to do with the gas you use, well always stihl or aspen. After that the guy just walked of and started talking to a friend. What ever...
Annny way, what are your experiances??? or solutions?

thanx maarten

Does it do this just when cold, or always? If you advance the throttle more slowly, does it still stall out?

Many issues could be involved, but as it's new, try turning the L screw a little richer (counter clockwise) until the saw accelerates smoothly. You may have to turn up the idle (LA screw) a little to make it idle smoothly. You've probably tried this though.

If the saw is under warranty, Stihl though their dealers has to resolve the problem... so don't take "no idea" for an answer.

You can prove your Stihl rep or wrong by changing the gas to the highest octane you have available locally (use Stilhs oil) and choose gas that does not have any alcohol in it.

There was a problem for a while with the accelerator pump on the C1QS61A carb. The current version installed on new saws here is the S61D and I've seen no problems with those saws.

Hi Andy,

Thank you for your fast reply. The temperature of the engine has no effect on the stalling. Yes, when you accelarate slowly or with sort intervals the motor does arrive to full.
The odd thing is that i have the impression that what ever you do to the L, L1 or H settings, it seems to have no effect to the gap in the exelaration.
Airways to fuel reservoir are fine.
Have you been having similar problems Down Under?

Greetings From the USA.
By the way, this post is going to cost you a bottle of your finest wine! 2006 or better. None of that old stuff.
As to your saw queary, I may be going out on thin ice here but what is your elevation? (In Feet) If my geography is korrect I believe that somewhear in France their is a mountain range. My memory is failling. What I am trying to say is that the saw may have been set up for a higher elevation.A higher elevation means the air is less dense or simply thinner.Now if you were at about 5k feet I bet the saw would run fine. Without more specific information I am unable to answer. After the saw is hot, will it sit and idle?If the saw fails to respond to the adjustments then I would look at a possibly kinked gas line.This could cause a shortage of gas at times. Keep us posted.Send the wine in a cushioned brown box, Ken in Texas

Here is another possible solution. I suspect that their is nothing wrong with the saw. I will try to explane. Their are two circuits to a carburator basically. Idle and high speed. If this anomoly occurs when the saw engine is leaving the idle circuit then it goes to the high speed side of the carb.Have I lost you yet?.Simply put, their is a small gap that will always be their. I would try and richen the low side and bump up the idle speed.If the saw will go to full throttle then all is fine.This is just speculation from my past experiance. I have know definitive knowledge on that specific saw. I hope this may help,Ken
