Would you mind describing your break in procedure? I realize that’s as bad as showing up in a firearms forum and asking AR or AK, but with any luck I’m a month away from breaking in a 57 364 and I’ll take all the experienced advice I can get.
That’s funny, scraping the old grease off old parts is one of my favorite things. It’s like sculpting for the untalented; just scape with a putty knife and before long a beautiful old engine emerges.
