Pulling the trigger or releasing it will make a sudden change to the load on the engine. If the engine cuts due to a sudden load change it might be the governor isn't responding quickly enough or more likely the carb is either partially blocked or maladjusted, though there is the possibility the spark might be weak or the spark plug worn.

Hi. I think you might be looking for the traditional brass flat head screw that is typically found and used to adjust engine idle. This carburetor should have a black plastic knob that you turn to change idle speed. Look where the throttle cable attaches to the cam wheel on the carb. The knob I mentioned earlier makes contact with that throttle cam. Please write back if there are any other questions. If by chance I misunderstood your request please provide more details regarding the problem. Also photos can be a big help too since sometimes different carbs are installed.

While I am not familiar with that particular motor, there are only two ways to change the oil in small motors. You either have drain plug on the bottom of the engine and a fill / level plug on the side, or you have to tip the engine up and drain it through the filler hole. The 2nd one is not very convenient, but some motors do work like that. I have a Honda motor that needs to be drained that way.
