Default RE: CRRC PRO GF26I

HELP!
This engine (26EI) runs great when it runs FORWARD! It loves to run backward! In fact when it pops, it throws the prop backwards and starts right up. Several HARD flips to get to go the right way. When it runs forward, I get great response, good idle, good transition to full. No problem there.
When it pops backward though, to breaks loose the prop bolt from the shaft and spins it off, prop, spinner and all, in one piece!
Any corrections for the backwards pop? Timing? Anything?
And the prop shaft unscrewing? 10 lbs./sq.ft. torque right?
Prop hub. (gold anodized) is fine. no cracks.
Any help would be appreciated.
