OK, Here's where I'm at. Went down to the Marina, Boat is on a lift so is easy to work on and test.
The first thing I did was, removed the oil line from the VRO. Pumped about 16 oz into a bottle. No bubbles, but super hard to pump.
The second thing I did was to premix my half tank of fuel at 50:1, just in case.
Put the oil hose back on, gave it last pump. Started engine and let get good and warm.
Engine starts well and seems to run well. (at the dock) After pumping the throttle up to 3k a couple of times and clearing the engines, returned to idle. THEN, the slow, beeeeep..............beeeep.......Beep....So while it was doing that, I squeezed the oil bulb nice and hard. Sure enough, beep goes away. It seems as there is a restriction somewhere between the bulb and the engine. The and pickup, bulb, & hose are new. Had to modify the pickup and filter a little when I put in my old tank. It was a little too tall. Pretty easy fix. (I had the beeping problem before then too)
So, I figure I will figure out the beep issue.
Next, I dug out my "Snap-on" timing light (w/tach) to start troubleshooting. The engine is idling too fast in gear at 1050ish rpm and I have no way to make slower. The linkage isn't touching the roller at that RPM and the "slow" setting on the timing disc is all the way down. So there's one problem. The timing at that rpm is 9 ATDC. Checked all cylinders for fire. All good. Have not down a compression test yet, because I forgot to take it with me.
Quick question on vacuum hoses and possibly vacuum leaks. When I was putting back together a goziilion times in the past, something doesn't seem right with a hose on the bottom. I realize there supposed to be one that sticks on a (broken off) nipple on the flame arrestor, but the hose I am left with has an open vacuum within it. I tesyed with a small piece of shop paper towel and it tries to suck in. That doesn't seem right. That hose is connected to a manifold directly beside and behind the fuel rail on the strbd side. There is another of the exact same on the port side, but it goes to something. Could this be the source of my excess rpm's at idle?
I have not checked the anti-siphons valves yet, but they a pretty simple. It's next on the list.
Thanks for the reply'ss so far!
