I would recommend not adjusting your floats (yes, plural) until you have exhausted other ideas. For instance, if there is any rust/crud in the tank that is migrating to the carb, it should be dealt with first...

Default Disassemble

Once you pull a carburetor off and disassemble it that will banish the bogey man of fear forever. It’s not complex.
Go for it. Carefully and methodically.
I vote for float height.

There somewhere is a series of posts bu XLForum member piniongear on adjusting the float on a VM38-9. My recollection is that it is a more precise process than on the Keihin carbs.

I've brought what I've found so far into the Sportsterpedia on the VM carbs.
Tuning and adjustments:

Most everything there is from piniongear I believe.

The float height cannot change by itself. Did the pissing out of the carb just arise? If the float height was off, it would have been leaking from day one. Isnt this the same bike you have been trying to get the timing and clutch figured out? It would have been pissing out throughout all of that time if you had the petcock on with fuel in the tank. Clean the bowl and needle out first before you change the height. Address one issue at a time.

It should not happen out of no where, if your float needle is clean and functioning and your tank is properly vented.
Cap vented??
