Geez, Bob, I ordered and installed the same list of parts (including a
Piper 270 regrind) from BPNW but have not yet fired it up. I'm still
awaiting my lightened flywheel back from the shop before putting it
back in the bay. Is this what I'll have to look forward to? So, when
you ask them, you're asking for others, too! We will await your
posting on their feedback. Lots of time and $$ involved, if this is
more than a one-off anomaly.
