Question about Ryobi 30 Cubic Centimeter Curved Shaft Gas Trimmer
Not many reason for this......One: your throttle is stuck open (I'm sure you would have found by now)..If not.... Its an air leak between the carb and intake port. The only purpose the carb. serves is to regulate air/fuel mixture and also the rate in which both fuel and air enters the motor thus maintaining consistent RPM stability while at idle all the way through to WOT (wide open throttle) when in operating....The Throttle body has a foil inside which opens and closes allowing air into the motor. The foil opens when throttle (lever/trigger) is applied and allows the air in that is needed to acheive appropriate RPM and power or to lower RPM when not needed. All engines WANT to RUN and the only thing stopping them from running away is the restriction of airflow....So if there is a leak between the Carb and the Intake port, then Carb will then be bypassed and the engine will **** in all the air that it is mechanically capable of through the path of least resistance, unregulated...... This is also extremely harmful to the motor because a "lean" fuel/air mixuture is caused meaning it is drawing in more air and less fuel which causes increased thermal combustion temps. and can burn a hole through pistons
