Ok, a few pictures.

First, the front outboard bowl with a dent in it.

And the inboard bowl with a temporary clear sight plug. Cost $4 each and should help with adjusting the float level. 

Before and after shots of the choke shaft. It was a little bent, and I carefully straightened it using a small block of wood. My choke is disconnected though, so it is basically wired in the open position. I cleaned everything up best I reasonably could, but still very tarnished and stained.

The throttle plates, shaft and screws. Not exactly streamlined.

Picture of the inboard jets...for comparison,,, my prior .080 jet on the left (about as fat as a toothpick) and my new .066 jet (slightly larger than stock). By my calculation, the difference in size is .066" versus .093",  Pi- r- squared means the .080 flowed almost exactly TWICE as much fuel. 

Why arent these needles replaceable??? Theyre plugged off at the top.

The broken needle I pulled out of my front outboard. Ordered a couple new ones off ebay today. Hopefully I picked the right type since these dont have any part numbers on them.

Pictures of meter block gaskets, existing blue one top left and the exact match upper right, but as with all these kits there are a bunch of additional gaskets. How do I know for sure the lower right gasket isnt the right one though. It has one extra hole which looks like it could provide a function, but    guess I have no choice but to use the exact match.

The fuel inlet needle and seat valves (old and new), both are .110.

I'm guessing this could have been my original problem. Notice the older type has a bigger plunger.

And finally, the finished inboard unit. Still ugly, but at least its cleaner.

For about $500 I guess I could get a brand new one, but for a total of about $140 in parts to do all three units, including all new connecting fuel lines, etc, it's worth a try.

I ordered two more .110s for the outboard carbs and I will be putting them together next weekend

Yeah, they arent pretty, but remember they are at least 43 years old, were last gone through about 10 years ago by the prior owner, and who knows how many hands theyve been wrenched with over the years..

Yep, carb cleaner and a tootbrush came in very handy. I dont have compressed air in my garage so using the cleaner to spray out the holes.

And yes I planned on swapping the float bowls front to rear. What do you mean lower # carb to the front?

You mean jetting?

All my outboard jets were at 86 BTW, and I plan to start with 80s initially, though I understand a perfect tune could easily end up with all different. 

I dont expect to get them perfect, just hopefully close enough to idle well, and not blow clouds of gas when I punch it.
