Sounds to me like it is running lean. Seeing how it is an alder model I would suggest doing a series of things that it probably needs anyway. Clean and overhaul the carb ( do it well with the help of a repair manual), drain and dry the fuel tank thoroughly, Clean the petcock, adjust the valves and replace the spark plug and air filter. Ehhhh.......go ahead and change the oil with a good brand of FULL synthetic oil .
