Re: Idle Speed Regulator



Big (3/4") wrong. Except for PCV, every ounce of air that enters your
engine should travel over air sensor plate. Is the only way to meter
fuel. Vacuum leaks (air entering engine other than over air sensor
plate) cause mixture to lean. Lean enough, and engine will die from
fuel starvation.

At closed throttle, air normally passes over air sensor plate, through
"forward" supply pipe, through idle speed motor, then into intake (via
cold start tube). If that pipe is loose, air will just get sucked from
outside world under fuel distributor.

Some DeLo O rings are available at hardware store. Others (like intake
manifold) are vendor only. If you want to avoid any guess work just
order from a vendor.

Note upper air assembly will need to come off to replace. Might
consider changing gaskets and O rings at U pipes same time.
