[DeTomaso] Carb question

[michael@michaelshortt.com]

If your engine does not idle up to compensate the load caused by air con
compressor check that your idle air mixture is working as this is what
raises rpm to prevent stalling and low irratic idle. Maybe just take it all
the way out, look for debris, dirt, etc. And put it back in ( count the
turns when removing ).
