Pretty neat, not that i needed it but the propane dual fuel is very neat.
My experience with everything pull start is poor but I put oil in it , hooked up the propane and pulled and it ran. Pretty quiet. Connected a 1000 watt heat gun to it and it revs up.
No endurance test but for the money i am impressed.
Now the only thing to do is connect an old egr cooler to the exhaust and make warm water at the same time
