I haven't run it at all yet Nitroholic. It's brand new and never been run, the guy that built it said he gave up on it! The Mad Rat runs fine but the Monkey is proving to be a bit of a Monkey!!
I've had it all apart, I've tried screwing things tight, leaving them loose the lot!
The driveshaft cups turn in the same direction when turned by hand, they should obviously go in opposite directions?! Should the nut on the slipper be loose or tight?
