I forgot to add that that I also have a Sthil HT 100 Pole Prunner and it starts fine just like the weedeaters and blowers. Someone commented that Stihl makes a great saw and I agree (after I get it started). Yes, I took the MS 170 into the Stihl dealer here in Kerrville and paid for them to do a complete tune-up. They said I had bad gas and a bad spark plug. They replaced the gas and plug. About 2 or 3 weeks later I tried to use the saw (with the dealer's gas) and I still had a tough time starting. Again, both of my saws run fine after starting and all of my other 2 cycle equipment start's and runs fine (using the same gas). Heck, I've even started using Seafoam to see if that helps. Nope!
I don't post very much on TBN - but - I read new posts almost daily and I really enjoy and respect you guys! I've learned a lot too. So, I felt like I could just share some frustrations!!!!!
Now - I feel better - again!
