Answer 1

most likely, the float valve needles & seats in your carbs are worn down, leaking a little into the engine, creating a rich mixture & flooding it out.

solution is carb rebuild with new kits.

But first, see if your spark plugs are fouled, and if the gaps are still correct (unless you're running surface gap plugs).  And all johnnyrudes run better on champions -- the NGK equivalent isn't an exact match.
