thanks guys for all the input...
rcken, i am goin to sand down the front end of the fuse (the directions say to), but that will only change the spacing of the ply spinner ring....the spinner back plate cant go back any further, so i think im going to have to get a thinner spinner and a regular nut to hold on to the spinner. but will the spinner need a washer before the nut? btw, the spinner im using is an airscrew 7x4 size which was suggested by the AP engine manual.
also, the prop didnt fit the crankshaft, but i dont have a reamer....would a drill be ok? and should the prop screw onto the shaft, or does the prop opening need to be big enough for it to slide on the shaft freely? thanks for helpin out the noob...
