Sudden high idle, rough idle, gas smell, very poor mileage
1985 Accord. 172k miles. Carburetor. Manual transmission.
Air cleaner recently disturbed to explore occasional carb icing problem.
(See http://www.misterfixit.com/carbice.htm)
Engine has been running well. **Suddenly** I have a high idle problem. Near
the end of a 20 mile drive on a recent cold day, stopped at a light,
suddenly the engine wouldn't idle down. Idling at 2K or more. I let out the
clutch and the car almost drives itself - little accelerator required. I've
not seen idle below 1.5K since. Runs rough, gas smell, and gas consumption
is off the charts. On cold start, idle immediately jumps to 2.5K or more
before idling back to about 1.5K. Fast deceleration or sharp left turn (!)
seems to cause idle fluctuation.
Why?
Thanks
Richard D.
************************************************** ***
An update:
Engine also diesels (run on) for a few moments after shutdown. Never seen
that in cold weather before.
Light colored smoke for a few moments on startup in cool/cold weather has
been an issue for a couple of years. Since the high idle began, there is
much more smoke for much longer time (several minutes).
While out driving this morning there was an interval of several miles where
idle dropped and the engine stalled several times. High idle soon returned.
Thanks for any available insight!

Re: Sudden high idle, rough idle, gas smell, very poor mileage
Off hand, I think there is a float level problem. May have dirt in the
float chamber, or leaky floats. Find a good (old) mechanic that has been
around Honda carbs before and see what he says. bob

Thanks for the tip. I've decided to replace this relic. Know anyone who
