New to Club: good day!
Where does one go in USA for best new engine deals....? Lycoming? Wentworth?
Or any reasonable overhaul-shops where I could buy an overhauled unit [or 2] without a replacement core?
Not from Wentworth. They have a reputation of selling engines with difficulties. Eventually, they will make it right. However, you don't want to go through the hassle and the extra expense, especially from New Zealand.
