Re: Speed Queen water pump? Model A engine.
Engineers eat numbers for lunch. We gotta have numbers. Here's a fictitious numbers exercise: a water-cooled 4-stroke that puts out 40 hp to the shaft at rated RPM (whatever that RPM is). Let's assume that the combustion efficiency of the engine is 40% and the other 60% is lost as heat. Let's furthe...

Re: compass location
Just looked at the pic again... I see that your compass is mounted just ahead of the rear spar. Got it.
Also noticed that you used my U-bolt trick on the cabane braces for mounting the passenger's shoulder harness to. How's that working out? Mine works great.
