I should have said measure from the gasket surface to the bottom of the float just as the tang starts to depress the spring of the needle valve.

Good find on the tank.

The cam chain must have the slack taken out of it BEFORE the valves are adjusted.
Turn the engine the proper direction until 15º past TDC then do the adjustment.
Read the procedure in the workshop manual.

See the photo of the crank positioning.
You will have to have a shop manual.

When you adjust the valves .002 intake and .003 exhaust.
So lets say you set the exhaust at .003, THEN try to slip in a .004 and if it fits it means the adjustment is still off. See what I mean?
Do not just use the .003 thickness gage and call it done.

Update - Been very busy and have not had much time, but getting back to it now. 

Still basically the same, but ordered new petcock (ebay), and new tail section and exhaust from carpy.

when tail section shows I'll be mocking it up, then ready for tear down. 

Need to get new tank cleaned, think I'm going to try vinegar first, it's in pretty good shape. 

I also need to find a source for TEC points/condensors to replace the Diachi ones, then I'm going to get Hondaman's ignition.

Anyone know where to get TEC points?

Those  early "F" models with spoked wheels are getting rare, i hope you are not going to butcher the frame and screw it all up. In my opinion that old girl should be restored, not cafe'd. That is a good original bike, i wish you guys would cafe basket cases and leave the good ones alone......

I agree with that. If it is all there and original, restore it.
If it is missing many parts or has too many parts beyond repair then think about cafe.

I'll just need to swap the tank lid lock from my tank and good to go. 

Those tank locks aren't keyed...you could open it with a screwdriver if you wanted.

I know you soaked those carbs but after so long sitting it's quite possible you have a plugged passageway in the carb bodies. Suzuki carb cleaner is the best I've found. Just use that and compressed air on the bodies and soak your jets in a little airtight container. Airtight is important. But I think you are on the right track troubleshooting spark first. Have you thought about throwing a dyna ignition and coils on? Those Honda plugwires can be somewhat infuriating when they age. Oh yeah DON'T get carb cleaner on rubber bits. Good luck dude!
