Has this unit has been sitting for a while ? If so with the throttle in the idle or stop position grab the governor arm then move it back and forth, It should move freely if not the throttle shaft in the carb. is gummed up and needs cleaning with carb. & choke spray cleaner.
If this is not the problem while your there checking look on the back of the block and there will be a model number for the engine, Post it for further information about adjustments.
