Nice machine, good packaging

Runs great out of the box You have to adjust the air intake and fuel mixture to get the correct vapour mixture for ignition to occur That,s the screw in cap on top of the acrylic fuel and water container and the chrome plated valve on the end of the non combustion cylinder Nice sounding exhaust Timing doesn,t seem that important
