Scat crank thrust bearing killed again

if you are asking me- NO
I see the champher trick is also in the tech doc referenced above
I've made oil pockets with a ball carbide and also cut banana groves diagonal with a dremmel and larger wheel- it's not fussy you just want to smear the face with oil
obviously when loaded all the oil wants to escape through the larger clearance toward the front- can't help that
most failures are crank finish related IMHO
