I've been through the carbs on this motor several times. WOT RPMs are low. This carb has fixed jets.
Recently I found the nozzle gasket was cracking apart and the three "arms" which hold onto the nozzle were breaking off/bent. For those who aren't familiar with this motor, it appears that this gasket restricts fuel from flowing through an inner passageway, forcing more fuel up through the main and idle nozzle. Can anyone verify the purpose of those arms? And where does this inner passage lead? I'm worried there may be a piece of the gasket up in there.
Also, I have never removed the core plugs when cleaning out the carbs. I remove the jets and blast carb cleaner through all the passageways, and clean them out with a piece of copper wire. Is it necessary to remove the core plugs?
I know that the motor is running rich, I had a friend following me the other day and said he could smell unburnt fuel. WOT RPMs are low, and she runs a lot smoother at close to the same RPMs if I pull back a little on the throttle from WOT.
