Is the problem being he is over reving (speeding) the engine or that 

the engine rev's are "hunting", that is changing RPM without throttle 

or load change.

I'm assuming that it has a C or E gearbox. If so the "driven" prop. gear 

is not splined or keyed to the shaft. It uses a tapered cone sleeve to 

tighten it to the shaft. I have heard of some of them slipping at full 

power. You can usually hear the ratio of prop to engine speed change 

like in the old days when the belt reduction started to slip.

Good idea Earl, the B box on my 582 also did that when it was new, 

except it was the gear on the end of the crank that was slipping. Lapped 

it in with some fine valve grinding compound and that fixed it.

Jack has a point here, if the fuel pump is not keeping up with demand at 

full throttle, the float bowel level could be dropping enough to lean the 

mixture causing the engine to rev slightly.  Between the lean burn being 

hotter and lack of lubricating fuel oil mix this could lead to a seizure on 

climb out. Not good.

Regardless I'll bet its one of the problems mentioned by Earl, Jack or 

myself, please let us know what you find.

All

I had a similar problem with my 582 in cruise rpm as it would search for a 

steady rpm. It turned out to be a to lean issue.  I put a larger jet in and 

it cured the problem.

That was the loose Crank shaft hub right?

I'm glad that I could point you in the right direction. Would you mind 

telling us what you found and how you fixed it? Did you just tighten the 

nut or did you have to replace the cone or use thread locker?? Which 

model gearbox? This kind of information should be shared and archived.
