I will go out on a limb and admit I am the one who gave Deve the tin foil trick to bring his bearing clearance to acceptable clearance.
Since I had little control over my machines work through the years, there were very few of the hundreds of engines I rebuilt or assembled that didn’t have at least one piece of tin foil in it.
It may sound like a redneck repair, but it works great, and if you are a sticker about bearing clearance, like me, you just have very few options.
