i got the ratchet adapter that works to the drill and bolt pice
Your "ratchet adaptor" is basically an extension rod, to adapt the socket to the drill's chuck.
The standard ratchet extension won't do this.

With your "adaptor", when the engine speed is faster the the drill, the flywheel/clutch nut will loosen up.

You need your adaptor and this adaptor:
Craftsman Ratchet Adapter 3052,30714,30721 You Pick Size(ts 324) | eBay

When engine speed is faster than the drill, this adaptor will freewheel,
preventing the flywheel/clutch nut from loosening up.

Equivalent to the paul clutch

My Briggs engine has recoil starter with paul clutch between it and the crankshaft.


China Girl Engine would have probably different part needed like 57H had mentioned Craftsman Ratchet Adapter, same idea though.

For gaskets without metal in the material I have from HF Tools a small kit of hole punches. I think if they are not exact size I need, your idea of using a grinding tool can fix that. A cone shape grind stone used with care I suppose can just stop at the pen marks?

Not sure what type of gasket material your using.
But grinding it can fluff up certain types of gasket material and ya don't get a clean edge.

Here is another Idea that might work for you
After ya use the hole punch
If your able to cut that gasket material with a razor knife.
Bolt the gasket over the hole and trim the edge with the razor knife.
I do that when I make intake gaskets

That’s largely why this forum exists, cause of people that think they can get something for nothing. Reliability usually costs around $1000 minimum...
