Kubota B2601 cheap and easy power upgrade ???

Today I was working on the driveway when I thought, today would be a good day to try propane injection on the Kubota. Does it need it no, but I had to try it and see if I could make it work!! At max throttle with no load it will pick up some rpm, the motor doesn't pull down when the land plane is loaded up with gravel. The really test will be with the wood chipper and see how fast I can set the in-feed.
