'the room full of saws' lot 020av has been giving me fits!

taking a brake from fooling with the carb, i recently pulled the jug to clean carbon out. while the jug was off i spied some crud that fell in the case so i flipped it over and sprayed it out with carb cleaner. i followed up the carb cleaner with a bath in charcoal starter fluid and a little mix oil, then dumped.

after assembly the saw still wouldn't run so i adapted an 028 carb to replace the junk oem and after days of tinkering.......
still no joy.

time for some new ideas:
i figured the residue from the starter fluid (odorless mineral spirits) was stopping the saw from running..... even on ether (yeah i know). i proved it by super flooding the saw by pouring mix down the carb. swish, swish, shake, shake, pull, pull and
pop! she runs! my best guess is that the mineral spirits that was trapped behind the bearings was re-flooding the saw with a non spark ignition vapor each time i tried to start it.

now the saw starts, idles, accelerates perfectly.

lesson: if you rinse the case, use mix for the final rinse!
