I have been running a 79cc gas engine on a SP11 all season 24x7.I just unhooked gas line from side of motor and made a gas tank out of a 5 gal. plastic jug by putting a small thru haul in the bottom of the jug and running a hose to motor.You have to keep jug higher than motor to gravity feed. I have to start engine with belt off and let it warm up a little, about a minute, then put belt on when running.should have motor on a hinge. Will run 26 27 ins. with no problem at a idle. Less than 1 gallon gas a day. Good luck Life is good. Vernon
