Al,

Could you have knocked = off a vacuum hose during your work on the upholstery, paint, etc. = =A0=A0Might be worth checking.Mark S.

No, drained the fuel completely a couple of months ago. = =A0Put in new gas after moving to the hangar.

=A0

It may be something = simpler; but the only thought I come up with so far is the mixture = mapping was somehow corrupted. =A0I=92ll know more when I get out there = and view the mixture mapping on the EM2.

=A0

Appreciate you guys = spending some time thinking about this problem.=A0 I=92m sure it will = get resolved. =A0I=92ll give a call when he=92s back and see what comes to his = mind.
