buy an impact screw driver for loosening any Phillips head
bolt or you could use the proper screwdriver and push hard on it, put an
adjustable wrench on the screw driver to loosen the screw
get the proper high quality puller for removing flywheels (under $15)
get rolls of gasket material from some place like Pep Boys or your local
hardware store and cut them to shape to save money
buy a torque wrench to tighten cylinder head bolts and other important ones
do not over tighten bolts or they will break or strip the hole, just make
them snug and use a little lock tight if you want
often the only reason for an engine not starting is a dirty spark plug,
even if the plug is not that old
use a razor blade to clean up sun-bleached plastics (just try it)
don't hammer on a connecting to get the crank unstuck, my friend did on
a yz80 and two days later the top of the connecting rod broke off
