If I understood your description accurately, an anti-siphon in the hose between the thru-hull and raw water pump would be counterproductive because it's designed to allow air into the hose under...

If you can get a valve to fit in there, have at it. Many Moyer products can be reverse-engineered and probably done a cheaper way, but we try and give some respect to our host here.

Don,

Fuel-water separator first. If there is water in the fuel it will make a mess of any filter that is not designed to deal with water.

Hope that helps,

More info

Don, on the stock late model carb there is only an "idle AIR adjustment needle" that adjusts the air flow to the jet for mixing. And unless you or someone has added the "adjustable main jet" there is...

I have a manual shut off valve immediately ahead of the carb in addition to the USCG required valve on the tank that's near impossible to reach or at least it's a PIA. A benefit you didn't mention...

Don,
If you can't do it under way, you're probably better off with a timing light and reving it in neutral - verify that the spark advances as the RPM increases. No need to load up those old...

The flyweights and their springs control the centrifugal advance. At idle, the spark occurs close to top dead center. As the engine turns faster, the fire needs time to get going so the spark...

Seems to me adding a sponge on top of the flame arrestor is a bad idea for three reasons:
1. It restricts airflow, performing the function of a choke to some extent.

Don-
That is most certainly not a "stock" setup and I'm not even sure if it'd pass the Coast Guard spec.
