Hello, my friend just bought an 85 prelude and when first started cold it runs fairly good except the throttle can't be just pushed halfway or all the way when starting out, you have to give it a little pedal and then slowly ease into it. Once the engine gets warmed up it can barely run and even floored the rpm doesn't go beyond 2 to 3000. It acts like it's running very rich. I suspect the choke isn't going off, but I'm new to these dual carbs with electric, vacuum, and the thermowax control and don't know where to start looking. There is the lever that sits outside the step plate that the wax rid moves, on ours the lever isn't connected to the round rod that goes up to a diaphragm? 0:41 rod going almost straight up on right side if screen. Any suggestions would be appreciated! Thanks
