Hello all I have a problem with my Husky 266xp when I go to start it, the pull cord is very hard to pull to start it. I thought it was seized so I took off the head and checked piston ring,and piston,and clylinder walls all look ok to me no scoring or scraping or broken parts?? Once I reassembled the head I tried the saw and away she went... After using it for a while it happened again, real stiff to pull recoiler??? I once again took apart head and same result all looks ok??? I tried to change spark plug and no difference,still hard to pull...I called a local dealer and explain the problem to him and he couldnt believe it. He did ask me to bring it over and he would take a quick look at it.When i took it over to him he couldnt believe what the saw was doing,he did a compression check and found that it had 180lbs of compression,and he said that its usually the opposite that u lose compression and not gain it.. He couldnt tell me what was wrong,so thats why Im posting here to see if anyone can help...The dealer gave me a 800 # to call for tech support and when I did they couldnt help me either??? All I can see is maybe a bearing is going somewhere in side and its causing the saw to lock up??? But who knows? Hope someone here can help....Thanks
