Re-tuning ms200t

[Nick Harrison]

Am having trouble with my stihl 200t lately, has not been running great for a little while and not had time to get it on work bench or put it into local workshop, had a frustrating half hour today tryin to remedy the issue in the p***ing rain and lost concentration/patience, now lost where all 3 screws were to start with and the saw is now hard to start. Been checking the plug to make sure not running lean as don't want to knacker the machine. Has anYone got advice on where to start re-tuning it? Have got the manual but it doesn't really go into much detail. Was thinking about buying a tachometer tomorrow to help work it out, anyone know if these can be used on the ms200t?? Any help much appreciated.

Turn both the H&L screws fully in (don't over tighten) undo them counter clockwise one turn, start the saw and adjust the idle until the saw idles ok and the chain dioesn't spin.

 

That is a very basic tune - if you can't tune by ear - I wouldn't bother with a tach as you still need to know how to get a basic tune before taching the saw.

 

If the saw won't run on these basic settings and the idle is up and down, it is possible you have one of a few problems with the notorious Zama carb.

 

Hopefully your local dealer will be up to resolving these or they will just fit a new carb.

Glad my old posts are still being used:thumbup:

Get it fixed and flog it or fix it and keep as a back up and get a new saw.

 

Only issue keeping as a back up is it wont like standing and will need something else doing next time
