Workin on mine right now.
Whats the trick to getting the wrap handle off?
Should come off easily, you'll have to drill holes for H+L screws in the cover but the idle already has one. Nothing hard as I remember. What muff mod did everyone do? I bent the fins open on the cover and drilled it

Hi Folks - Hoping someone can help me here... I did the exhaust mod and installed a WT-215 carb on my MS170. It idles great but when I whack the throttle open, it bogs and dies. While the H screw adjust does seem to make a difference in the running of the engine, it does not get rid of the bog. It runs good until warm, so I am guessing that it's a rich bog? Any suggestions?
Did you pull the brass plug in the impulse circuit?
Slap a MAGNUM sticker on it and then you'll really have something to brag about.
I saw that plug but couldn't tell if the OEM carb had a complete passage or not. I have not messed with it. What does that do, meter 'draw' on the high speed circuit
It’s the impulse passage.
Pull the center plug and block the side one with sealant
Finished product - does this look right?
Cool thank you! The trail gods will be happy today!
Let me know how runs now
To get rid of the bog, you richen (back out/counter clockwise) the Low screw (closet to the cylinder). Not the High.
Generally you back out the low screw until you hear the revs just start dropping, then turn it back in just a hair.
Did you read anything here or just post based off the original post?
What kind of sealant did you use to block the side hole? UPDATE: I read I can use “Plumbers sealant”!
Another question though! Do you have to pull that plug on all WT-215 carbs when you put it on the 170? Or are some of them already open there?
Any chance someone can throw up a link to where there getting there WT215's from, All of the ones i look at on ebay don't say WT215 but look correct, Like this: https://www.ebay.com.au/itm/CARBURE...340429?hash=item35e8c2b24d:g:1IIAAOSwWm5dRMZZ Can anyone confirm this is the correct carb?
Go to Amazon, type in wt215 carb!
Hi all, I have just fitted a Chinese copy of the Walbro 215 carb to my Ms170. It took a bit of tweaking in the adjustment screws to suit my Australian conditions but the saw is a lot more throttle responsive. It was getting late and I didn’t want to disturb my neighbours by trying it in a piece of solid wood but I’m confident that it’ll be a big improvement. Muffler mod to follow soon
