I bought the tiller for $10. Took the motor off (5hp Briggs) and put it on my Trav-Vac for my WB. I was in a jam last fall, so I was rushing to pull the old Trac-Vac engine off, and put the newer one on. Well, you guessed it, I'm putting the original Tiller engine back on. Everything is great except the belt drive. I'm not sure if I'm missing a peice, but I know its not right. The pulley isn't tight enough to the shaft. The tiller claws will turn when in the air, but once I put it on the ground, they stop, because the belt isn't tight enough. And it worked perfect before I removed it. I am stupid or what! Here are some pics.
