Ross,
Sorry about the accident, but glad that no-one was hurt, it will give you something to tell the grandkids later, I have checked my instruction and maintenance manual for 2200 jabiru engines and under 7.6 prop strike inspection it reads,
"Afterground contact of a wooden propellor, check the crankshaft and flange for runout at the front seal surface. If runout is evident, the engine will have to be stripped and crankshaft checked for cracks. The flywheel bolts [6 off unf cap screws] will also need to be replaced ".
Hope this is some help to the rebirth of the cheetah, all the best.
Brian
