Jonathan:

There is a problem with the FI on the air cooled
2 liter motors.  It is starting when cold at
high altitudes.  I'm attaching something I wrote
about it a while back.  I have never had trouble
when warm, so check what has been advised.  My
big "S" hose from the AFM to the throttle valve
had a crack at the bottom, so you could inspect
it and think it OK, but it really wasn't if you
took it off and flexed it.  Let us know what you
find and good luck!
