ms201T Performance Question

[GardenKit]

To be fair though, I am also finding that many users who would have just bought a new 200t if they were available are repairing their old 200t rather than buy a new 201T at present.

 

But Skyhucks also right, there is only so much you can do (economically) to a worn saw. It can be fixed up to a point, but its still a tired saw.

 

There will come a time.......

The new Husky is going to be a game changer if it lives up to its promise. (and is ever released)

 

I have been a Stihl man through and through, but had the Husky on trial and was VERY impressed!!

No, you said they were no good.

 

I don't believe so, I suggest you read my post again, I just gave a possible solution to the OPs problem and said I have seen a big up-turn of people wanting MS200Ts refurbed.

 

I havent used the 201 but have stripped, repaired, ported, muffler modded and tuned MS200Ts - I can only pass judgement on the MS200T and not the 201 and believe that is what I did!

When the MS441 first came out there was some tuning issues. I wonder if the 201 suffers from a similar tuning issue.

 

From Sawcollector on another forum this works well with the 441 may take a similar process on the 201

 

Gently warm it up. With a tach set the idle to about 3300 RPM, then find the lean drop off point with the L screw. That is where the RPM drops off lean if you go clockwise any further, and also starts to drop off when you go rich by turning the L screw out. Once you find the L screw lean drop off point and the idle is at 3300, then use the L screw to fatten up the idle to get to the desired idle speed of 2800 RPM, not the idle speed screw. Once you get that done you will find that the saw idles well and will have crisp throttle response and is at it's optimum mixture setting for idle and off idle. Then go to wide open throttle (WOT) just long enough to see what the tach says, don't hold it there very long, and go from rich towards lean to get to no higher that 13,500. The module will take away every 8th spark above that so you can get too lean but it won't over-rev, so always go from rich, say around 11 or 12 K up to 13,500. If the carb doesn't tune sensitively then there is a fault in the carb or an air leak or something else wrong. When I tune a 441 this way it runs good
