Randy. You can do things. 1. Apply Carb heat on the ground whenever you accelerate and when you land. Yes, you might get a little less power for an eventual go-around. But better less power than none. Ones you are in full power mode or idle, close carb heat again.
2. Adjust the idle mixture at the carburetor. It is the small curly screw at the throttle body. Try to turn it out 1/2 turn steps, then try if the engine runs better. If that does not do it, you need to consider cleaning the carburetor. But using carburetor heat is a simple work-around when the idle mixture appears to lean. Which it is in your case.

My Ercoupe is a '46 415-C with C-85 with O-200 crankshaft. When it's below 40 F, with the engine warmed up, if you push the throttle in even a little fast the engine will cough and sputter. if you push it in fast you can even kill the engine. The other day just after I landed I goosed the throttle a bit and killed the engine right on the runway. It idles great and has great power in flight.Engine run ups are normal. Static RPM is normal. My carb has no accelerator pump or mixture control. In warm weather I have no problems at all. It did this last winter too, but when spring came I forgot all about it. Anybody have any suggestions? Mine is the only airplane that I've had any experience with so your help is welcomed. Thanks, Randy Hougham Grandpa's Ercoupe NC87384
