Getting ready to do my first annual on an io-540.
I realize I can borrow one but really like owning my own tools.
Started to look at these units and there seem to be multiple versions depending on spark plug bore, etc.
Bases on your experience, what's your recommendation for a compression differential tester for a stock lycoming io-540
Thanks
