It has been mentioned before but worth repeating:  This problem is not
uncommon for the IV.  My fix:  ALWAYS start the engine on the left tank, and
during taxi on the way to run-up switch to the right tank.  That way both
lines from the tank are "locked and loaded" before takeoff.  Have never had
any further instance of loss of fuel flow to the engine in flight in the 8
years since instituting the procedure.

Cheers,

Doug Johnson

"yet again today, the left tank skipped upon switching from the right...very
disappointing and unsettling to say the least.
