I'll leave the electronic issue to our more experienced members of this forum.  The issue of stripped screw holes can be avoided by a simple procedure upon re-assembly.  When you insert the screws in their original holes, take the time to slowly back out the screw a turn or so, while applying no pressure to the screw.  When you feel the screw slightly rise and then fall, you've found the original threads that were cut when the unit was first assembled.  Follow those original threads, and you can re-assemble the unit without cutting more threads.  The more threads you cut, the weaker the screw will be in the hole.  If you feel a lot of resistance, that is, you need to apply more torque to insert the screw, you are cutting more threads.  When more threads are cut, you are essentially making the hole bigger by weakening the plastic in the hole.  On the older AF items, previous owners didn't heed this simple piece of advice.  And it took me a while to come to MY conclusion on the threads. 

I'll second (or third) the advice on the Dallee reverse units.  Good luck on yours.

 

Been doing that for years! Especially useful on engines that are problematic and require frequent servicing, or even just following up on some previous gorilla's repair efforts!
