Thanks for the info,
I have a stihl 017 that I use to trim with around the mill and I have a poulan "wild thing" that refuse's to run once it gets hot.
local chainsaw guy say's my poulan has scared cylinder walls because I was running the stihl mix instead of poulan...
I wasn't going to buy the husky if I had to carry two different mix's with me.
I plan on buying a nice stihl with a 20" bar this fall when they go on sale at our local farm store.
Thanks again for the input.
