idle actuator

[ralexander03@snet.net (Rick Alexander)]

Ron brings up a good point. Vacuum can be lost in the damndest places. Was
everyone aware that the dipstick guide tube is a vacuum control device. It
seals the crank case closing the loop from the breather into the intake.
There is another obscure vacuum item that you wouldn't suspect to cause an
idle problem but I just can't think of it now. Anyone know?
