Stuck

[Richard Strecker <dmc1219@xxxx>]

Is there a cure for a sticking idle motor?

I've been having problems lately with the idle not returning to ~750.
Sometimes it will run at 1000 rpm other times somewhere between 1K and
1.5K. I noticed that the hose link between the cold start valve and the
idle motor was a very sloppy fit, so I replaced it. While I had the
idle motor off, I noticed that there was l lot of dirt? carbon, gunk,
whatever in the passage. After a few shots of carb cleaner, the passage
looks pretty clean. Cleaned the electrical contacts & resealed the air
pipe, reassembled everything.
Started the engine & idle seemed OK, gave it a quick hit with the
accelerator & back to high idle speed. In somewhat desperation I rapped
the idle motor with a screwdriver handle .......the idle speed returned
to normal. I've tried this several more times and every time the
screwdriver works.
This may get a little awkward while driving if I have to get out & whack
the idle motor at each stop light. So, other than replacing the idle
motor, are there any suggestions????
