Engine was running super lean, have the nuts turned down six turns to far. I think it's a bit too lean yet but it runs, had to adjust the idle screws, rpms was too high. I'll install a small tach and play with mixtures next. If I remember there is an idle screw on each carburetor. Then there is a screw that adjusts just one for the purpose of synchronizing them.

The brakes have an issue, one of the brake reservoirs goes empty when I pump the brakes, got a leak somewhere, didn't see anything dripping on the floor. One problem at a time, engine first. Are master cylinder rebuild kits still available?

I wonder if the needles are set too low in the pistons? Closing off the fuel with the choke off

The needles are adjust correctly, one takes a straight edge along the piston to make sure the shoulder on the needles are correct.

There is a lot of history here, had a very difficult time getting the needles and floats adjusted right in the bloat bowls, that took an enormous amount of time.

I have a tach on the coil, next is to turn the nuts to go on the rich side, then rock back and forth to lean, looking for max rpms, at least thats what I understand.

I've been running fuel out of a 5 gallon gas can, the excess goes back into the main tank, ran my gas can out of fuel. The fuel tank is somewhat rusty, need to find if it is usable or now.

I discovered something I was doing wrong. On the bottom of each carb is a small button, the service manual calls it a "lifter." By pressing it with one's finger, can raise the piston slightly, I think the purpose is to make sure the piston isn't stuck. By pressing on the lifter, the piston goes up along with the needle. Logic says that would make the mixture more rich, so I thought and I would use that method to determine if my mixture was rich or lean, bad idea.

The manual says to turn the nuts 1/8 turn at a time to find the max rpms. I think I'm in the ball park, I need to find where I get the highest rpms by adjusting the nut on each carb. Once I get the mixture proper, I can return to setting the idle speed and the balance.

CO was very helpful in getting the floats adjusted, I ended up per his idea of adding weights to each float.

If I'm on the wrong track, please let me know, I'm open to suggestions.
