When I start up my 1988 Honda Accord, It runs just fine as long as it is cold. However when it warms up it will not idle. It drives down the road just fine but as soon as I push in the clutch it dies. Checked for a vacuum leak with Brake cleaner, no such luck. Sprayed Carb cleaner everywhere that I could without completely removing the carb. Thinking that the automatic choke might be going out but not sure what to pursue next. Any pointers would be appreciated.

 

the difference between a cold and hot carb is more fuel. a hot carb will meter less fuel and that could be the reason why it's dying. If it has been sitting a while the jets maybe clogged. I'd try to take it apart and clean everything out with carb cleaner.
