I corresponded with him about a year and a half ago about porting a 661 for me. Yes he is “cautious” about who he ports for, I think partly, he does not want to be a slave to his work bench porting in all his free time. He’s a faller not a full time mechanic.
We went back and forth via email and then I never heard back from him and a bit later he posted his last YT video in awhile. So I have no issues with him, I reached out to him, he’s not advertising “porting services”. Everyone has their quirks but Jack Beelar has earned his status or whatever you want to call it by being a faller for as long as he has been doing it without getting seriously hurt or killed. His videos are priceless.
