Well, just got my azz ripped for using silicon to rebuild a saw with. I have a old 55 huskey, I have worte about it in other threads. Anyways, I had rebuilt this saw 3 times trying to get it to run right. First time was with a china p/c, the second time with a cp Hiway kit, and this time with a new oem p/c kit. I have way more in this saw than its worth, but I refused to be defeated. Anyways, Having ran out of good gaskets, I decided to put a little silicon on the carb gaskets and reuse it. I took great care in making sure no glue was in the impluse tube and was very sparing putting any glue on the gasket. Saw cranked and ran like new. test cuts on small dia wood and I was smiling ear to ear. Finally I had a saw that would run. I then stuck the saw in a 30in dia white oak, Saw was cutting best it could considering it had a wornout safety chain on a 18in bar. About halfway thru the log, the saw changed tunes, like the carb was out of adjustment. Well, having burntup one kit (the china kit),already. I just cut the saw off and waited till this morning to take it to the shop. Well, they pulled the top cover off and seen the silicon and started giving me heck. Took carb off and took apart and inside the carb was silicon. Removed jets and washed silicon out of the jets, out of the screen and just about every orifice in the carb. Put everything back together and saw again runs like a new one. I got to hear how the swedish spent million perfecting the build on those chains saws and how you dont see any silicon on a new saw. I was asked questions like, "Do you think I'm smarter than the folks that built the saw. And a few more comments that just aint appropriate for a public forum. Oh well, It took three attempts, and a little friendly ribbing, but finally the saw runs like I think it should.
