Question about Poulan Pro PPBP300 30cc 2Stroke Gas Powered 180 MPH Back Pack Blower 952711971
A two-stroke engine idles because a very small hole behind the throttle plate lets a tiny amount of gas through to keep the engine running. At full throttle the air moving through the carburator pulls gas through the venturi vaporizing it. With the motor at idle, if you give the motor full throttle very fast the first charge or two that get into the cylinder are almost completely fresh air with vary little or no gas mixed in. It takes a revolution or two for the motor to pull air through the carburator fast enough to get a fully charged mixture of gas and air into the cylinder so you get full power. This effect is especially pronounced when the motor is cold, the gas doesn't vaporize as well when the motor parts are cold. If you give it throttle slowly or let it warm up the effect should go away.
