I just picked up an 18xd, electic start model, as a spare engine/parts donor for my 25xd. It has been sitting for a while. The gentleman I bought it from told me he put a carb kit on it but he could only get it to crank and run with the throttle open. It has been sitting for a while but I'm not sure exactly how long it has been since it ran. I cleaned the carb, changed the plugs, and hooked it up to some fresh gas.
I spent a while priming the carb, cranking it, and the motor would fire up and die. It did that repeatedly. It finally cranked and ran when I held the throttle open by pulling the control lever forward. After it started running I let go of the control lever but the motor kept running at a high rpm. After about 15 seconds the motor did not drop in rpm so I turned off the ignition.
What kind of issue does it sound like and what might I be able to do to remedy the problem???
