Well, I put it in wood. The saw did not blow up. Was idling at 2700 12500 WOT. Cut three cookies with it, ran pretty good. Took it into the shop pulled the plug.......pure white! Surely it must be an air leak to make it do this. Pulled the saw apart again and did another pressure/vacuum test. Started with 80KPa to 4.5 minutes to get to 60 Kpa. Did Vacuum test 60 Kpa close to two minutes to get to 50 Kpa.

Has got to be an air leak somewhere but can't find it, only things left to test are the carb spacer.
That sure didn't show a air leak?

It didn't show a problem with the high speed nozzle check valve either.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
