Chainsaw Repair

had a learning curve with some sealers.  my experiences might not be the same as others.

for paper gaskets:  found over course of time, that the old standby 'indian head shellac' is very cheap and always did what i wanted it to do.

for copper gaskets:  spray copper.  this stuff is very messy and runny.  after blowing out head gaskets a number of times, found that spraying the gasket, on both sides.... holding gasket up by a wire through one of the stud holes..... and letting the stuff almost dry completely before install, finally worked.

copper gaskets can be a pain to cut.  tried exacto knives, sharpened pizza cutters, linoleum cutters for these.  cutting them on a mud flap.  i like using them, however because sheets come in different thicknesses.  an assortment of sheets are usually cheap, (or were, have not bought them in years).  as far as copper goes..... i always thought it was used because it was a good thermal conductor.

rtv silicone:  could never get this stuff to seal anything because i was always in too much of a hurry to let it set long enough to get thouroughly sticky before tigtening bolts.  if i use this stuff, i tighten bolts, then take the bolts out to remove excess goo that got squeezed out the sides.

imo, hylomar is real good stuff.  gascacinch will seal anything...... sometimes too well.  if nothing else will seal it, then resort to that.  aneorbic(spelling?) worked well for oil pans, but have not used it for much else.

yamabond: the only thing i ever used it for, was for harley cases.  thought it was kinda thin and very stringy to work with, but it did work well.  can say to use this stuff sparingly, it oozes like rtv.
