As Paul Harvey says, here is the rest of the story. I installed a new set of heads on my Revmaster and I dropped a 12mm nut in the
intake manifold. Started up and ran fine, made a trip around the patch and ran fine, made a 180 mph pass still good but, after I turned base, it started shaking bad so I throttled back and took a short cut to final and landed. Found the cold cylinder and pulled the # 3&4 bank and found the nut wedged between the valve and seat holding the intake valve open. Installed new valve and seated it in. Running fine now. Caution!! do not have too many helpers standing around while you are assembling your engine as, it can be a distraction.

I don't like finding parts I haven't accounted for when I finish putting an engine together. -Jeff Scott ---------------------------- There's more to this story - the answer as to why the nut didn't just pass on through the exhaust, but I can't recall why it didn't. The moral of this story is to be very curious about the whereabouts of any missing fasteners or other small parts when putting an engine back together. If the missing nut had showed up just after liftoff there would have been a different end to this story. Maybe Sparky will chime in with some better detail . . . .
