It takes me 3 to 4 times to get the engine to continue to run after starting. It starts okay but the RPMS quickly drop off and chugs to a stop. Pump the gas pedal a couple of times and try again. About the 3rd or 4th time it slowly picks up RPM and fast idles okay. Once warmed up this old thing runs great ! There is one thing that it does that bugs me, but that's for next time.
