Modding the new MS201T - The truth inside

[wdstruble]

I'm a little late on the conversation . We have a family owned tree service in jersey always used stihl saws . We bought a couple of the ms201t for are climbers we were not happy with them.started buying old 200's and refurbished them. Since finding this sight and finding out what you guys said about the ms201t would like to try to modd them did muffler and carb trying to figure out how to advance time them I know you mention how to do but can't find that thread

So has anyone actually been inside the cylinders yet to check the port timing and squish?

I have done the carb and muffler, and moving to timing next. If that doesn't solve the power problem for my tree service guy I'll likely be going inside for a route around if you know what I mean.

You don't need a thread on how to do this brad pretty well explained it on the previous page.

1.) remove flywheel

2.) shave 1/3 the width of the cast in flywheel key (from the right side of the key while looking at the back of the FW). You have to remove it from the correct side so that you can turn the fw counter clockwise 1/3 of the key width.

3.) reclock the fw and hold in place while tightening the fw key so that the fw timing stays advanced.

"2.) shave 1/3 the width of the cast in flywheel key (from the right side of the key while looking at the back of the FW). You have to remove it from the correct side so that you can turn the fw counter clockwise 1/3 of the key width."

Is that 1/3 of the flywheel key when the key is at the 12 o'clock position, or when it is at the 6 o'clock position? And, when you turn the fw counter clockwise, is that while looking at the back of the FW, or when it is installed on the engine?

I know the answers, but maybe some newbies might not have thought it out and could get it wrong.

12 oclock
front during install

This is confusing at best,--it would be the right side if the key were "UP", but it would be the left side if the key were "DOWN", go with "CCW facing installed" and you are moving in the rite direction--in order to advance the timing, the "Flying" magnet on the flywheel needs to get to the coil "sooner" relative to the piston. I put up some pics of this, with an arrow showing where to file on the key. look at: http://www.arboristsite.com/community/threads/thankyou-brad-re-201t-mods.258819/

Also, I've done 3 so far, the results were great, and once I rigged a mini degree wheel, I found that 6 degrees is probably ideal, but since this stuff cuts fast, i did file one around 7 and another at 8+. Neither me or my partner could tell which one was which, in fact the one that degreed at 7 ran the best, but it also was a bit newer than the other 2.

Question: So if you do just the muffler mod with the spark arrester removed do you have to take the limiter out to get a gain in performance from the muffler mod?
Thanks in advance!

 

[benmyers]

If you take the screen out and drill a hole, you HAVE to get rid of the limiter so you can richen it up. They are lean enough as it is, that will make it very short lived.

Actually, I leave the spark arrestor intact. I replace it after adding the additional hole. You will definitely want to remove the limiters on the carb needles though. Set the L at 1 1/8 and the H at 2 1/2. Fine tune from there.

Brad, When you do the muffler modd, do you also take a modd in the waffle inside the muffler? (The same we di full muff modd on husky 550)

 

[Gypo Logger]

Brad, loosen up the chain and crank up the oiler! Otherwise a fast Lil saw.

Yeah, she looked a little dry and tight didn't she.

Been a couple of years since I got a snellerized 201t….just here to say….Still super stoked, has been a GREAT saw no problems whatsoever….No affiliation other than a happy customer. Thanks Brad!
