Default Hercules generator

I have a Hercules engined military 5kw generater set, dated 1961. I am guessing it is a ZXA from reading postings on this web site. It has an updraft carb.

My question is what is the correct setting for the carburator' high speed needle? I have trouble keeping the engine running after I start it.

Also, the magneto firing order is 1-2-4-3. Which cylinder is Number 1? the flywheel side or the water pump side? Does the magneto turn clock wise or counter clockwise?

Thanks
Jim

Number one is on the water pump end. There were 3 gear and 5 gear Hercules engines. Best way to tell on the mag is to turn the engine in direction of rotation and with the cap off the mag see which way the rotor turns. On the screw start with a 1-1/2 to 2 turns and see where it gets you.

John
I set the carb to 1 1/2 turns and the engine fired right up. Thanks again. You saved me lots of fooling around and wasted time.

Watch that rotor rotation; it's opposite the magneto shaft rotation. The impulse coupling should produce a loud clack at TDC of #1 on fire stroke.
