[pooch]

My pilot engine has locked big end inserts.

I am yet to find if all or only some or none have these .

Mine could have had a crank change .

Will be very curious as to whether this thames engine when it arrives has them or not.

My last flathead was a 1946 C69A and it also had locked imserts.

I did ask an old dude who has overhauled 2 pilot engines and he sadi both had floaters inside.
