decompression valve is stuck, trying to get it out without removing cylinder. been spraying it liberally with kroil and have seen some VERY slight movement. SM indicates the valve should come out easily. Not happening. just trying to make sure there are no keepers I'm missing before I bring my MFH out. would a torch be helpful or hurtful? anyone got any ideas?

Edit: got it out. had to drift it out with a LFH. turns out the previous owner or mechanic had dinged the end of the plunger just enough to alter the diameter. apparently had to force it in. I cleaned it up with my bench grinder. works great now. whodathunk?

oh yeah. light weight with an attitude
