I ran four tanks through it using a 10X6 prop and now have switched to an 11X6. I ran four tanks through it and leaned out the high end a little more on each tank. On the third tank I was able to hand start it ! Then I ran it up to full throttle for a few seconds to get an rpm reading . On the fourth tank I leaned it out a little more and the transition really improved and it even idled well. Next step will be to install a 13X6 and run a few tanks through it using that prop. So far so good !
