'81 Westy 2L aircooled, manual trans.  Runs like a dog
when cold, it idles fine, but acts like it's running
out of gas, or the ignition is shutting down when
accelerating, big time hesitation, won't take any gas
at all and sometimes dies.  She runs great after a
llllooonnngg warm-up.  So far I have replaced the fuel
pump and filter, blocked off the EGR, Checked the
AFM/temp sensor with a multimeter, auxiliary air
regulator, cylinder head temp sensor, and freshened up
the distributor, everything was hunky dory.  I don't
think it's the O2 sensor since the idle is fine at all
times, and I believe the O2 sensor only comes into
play below 3000rpm, but could be wrong. Thanks in
advance for the replies.  Oh by the way, I live in
Southern California so when I say cold I mean an
outside temp of 50-60 degrees farenheit.
