Here is the specs on my Honda. 1987 Honda Accord LX with 78,000 miles on it. Bought it from an old lady who babied it. With that said, its the old shutter after it warms up at a stop idling issue. I have sprayed carb cleaner, added sea foam, adjusted timing and even took it to a mechanic who says...thats just how Honda's with carbs run. Well I am listening to any ideas. I have searched the net and found things from a back motor mount to turn up idle to plate on bottom of carb is letting in air. Checked them all and same answer. Today checked timing and vacuum advance and its fine.

But when it starts it idles high and calms down then is fine just until it runs enough to be warm and then at every stop it shutters. Please help.

 

Welcome to the forum,sounds to me like maybe a carb rebuild is due,When you used carb cleaner did you spray the carb and let sit for 10 min first? letting it soak loosens varnish,then start car and with throttle opened to 1500 rpm spray the throat with cleaner till the can is empty.Do this and also spray the linkage. Let us know what you find, good luck,Bobby.
