Thanks Kind Sir! I'll give it a shot..
This worked great for me except for some goof ups on my part. At first, I bought the cheap knock off wt-215 on Amazon. I couldn't resist that it came with all those goodies like replacement fuel lines, fuel filter, spark plug, etc. all for $12 including shipping. After installing it, the saw would die after starting up. Thats when I found Brad's instructions here. The cheapo carb didn't even have a center impulse passage, so I bought a genuine Walpro and epoxied up the passage that was katy-corner on the housing, and drilled out the plug in the center passage. Turns out that had the same issue: the saw would start, then within a few seconds just die. I pulled my hair out trying every carb setting, then even pulled it off and put the original carb back on. Same issue!. Then i reversed the timing advance I had done. Finally I figured it out: The cheapo carb came with a gasket that blocked the center impulse passage. I left this on when I first put on the cheapo carb. Once I removed this gasket, the saw fired right up. Another tip: When I re-enabled the timing advance, I cut a small wire and carefully pressed it into the gap before resetting the screw - this helped assure the advance wouldn't slip back when I tightened the screw.
Just did two 170s. WT-215 is the best upgrade. Worth the money on these low end saws
How do you go about doing that?
Parts from China take weeks to get here and the tracking doesn't show progress until they clear U.S. customs. This guy may have scammed you but if you are impatient, you shouldn't order anything from anybody with a long shipping time because it is probably coming from China.
I have bigger saws. I have a MS 391 and 500i that I installed a bark box on. All 3 run great, but what's wrong with trying to get the best performance out of them all?Sheesh…these are $200 (brand new) 170s. Just open up the muffler and be done. Done this many times…cut up 30” logs with the oe 16” bar…
Need more? Get a bigger saw.
My next saw will be a MS 261 C.
Swapping carbs won't enhance performance on a 170. Just say'n...
No, but opening up the exhaust will and if that makes it too lean, it could eventually destroy the saw and the adjustable carb could possibly keep that from happening.
I may order one of those carbs this week. I think the 170 is a little beast of the box but I'm always tinkering with something to get a little more out of it.
