Noobe to MTF. Pleased to meet ya!

Been working on 4-cycle & 2-cycle equipment for 40 years- 30 as a hobby and 10 because, as an unemployable manufacturing manager (salary history and not willing to relocate, primarily), I've contracted for golf courses, landscapers, JD distributors, etc., and having a time of it!. As a big-box, house-visiting technician, I discovered that they do not want to support older machines. I handed out cards, and when laid off, started my own repair/refurbish enterprise. I hope I'm not stepping on anybody's toes. But out of my league on some the the aspects and looking for counsel. Glad to be here.
