I have a used O-320-D3G in my RV-9A. I'm working on the baffles. Under the left baffle on ramp, there is a support that screws into the engine block. The screw hits a hard stop after screwing it about half way into the engine block. About 3/8 in. of the threads are in the hole, and 3/8 in. of the threads remain outside the hole. This is like all the other 1/4 in. baffle screws.
Of course I can't tighten down the ramp support without being able to thread the screw in much further.
I poked a nail in the hole and the hole is over an inch deep. So it is not hitting the bottom of the hole. Should I take a tap to the threads in this hole?
Any other suggestions? Here's a picture of the hole I'm talking about.
Thanks for any help,
