I have a 20+ year old Stihl MS270 chainsaw. After changing out the coil and carb, still no start so I invested in a Mityvac compression tester. Got about 120 psi, which from what I have seen, is probably the culprit. I am trying to remove the top end and find the 4 T25 bolts to be resistant to my efforts. Usng a drill/driver. Tried a little heat to see if that would help, assumng there is threadlocker on the bolts, but no success. Looking for any advice to disassembly. Thx
