Had a customer bring one of these in, and truth be told, I have yet to work on one of these old beauties. Was just wondering what reasonable compression numbers are since this has the pressure relief valves on the cylinder head?
I had 45/50 T/B hand cranking, and the motor has been sitting for at least 2-3 years unused. The rest of it is checking out for the usual repairs but I have the A-OK to fix the motor as needed to turn it back into a daily driver for a vintage boat piece.
Even at 45/50, this thing is a bear to pull over and cranking speed was pretty slow despite my ‘strongest’ efforts to do it manually!
