For small engine repair kit, looking to create drill and tap set, mostly for drilling out holes which have been permanent thread locked needing hole cleared and threads chased.

Information didn't easily come to light using search function on forums, determined would discover and list tap and drill sizes preferable for HT CG kit engines.

Monitor this thread as discover/make available updates, as they're found.

PS: Got a little bit lazy, purchased thread chasing tap set, for less than $10.

If this isn't enough to cover MB thread's, then I'll post update.

Those look like Taps
It's not a good idea to use a tap to chase threads You'll just end up cutting the threads more and weakening them
The threads will have a greater chance of stripping (pulling out) .

To chase threads use Thread Chase Tools to clean/restore the threads

Pic is just to show ya what thread chase tools look like
