Let me rephrase the question.
If you remove the tank from the bike and turn on the petcock, then fuel
should not flow.
I assume that this is because of the vacuum dependent feed.
During prolonged periods of storage, I like to run the carbs dry. Turn off
the petcock and let her run. Just wondering
My understanding has been that pressure from that fuel can/will put a ring
groove of the needle as it sets against the seat of the jet. I almost always
turn my fuel off. I forgot to this summer & that is part of the problems I am
having now. Will idle but not accelerate. Carb #4 is screwed up.
No. The vacuum, or technically the lack thereof, allows the valve to close and
stops fuel from flowing downhill into the bowls. IF the float valves are
perfect, it shouldn't allow fuel to bypass...but they do! That can flood, run
into the cylinders, and past the rings into the oil and ...BOOM!
Was wondering is it overkill to have a petcock and a vacuum feed?
Since fuel only flows when the engine is running, doesn't it automatically
shut off when the engine is turned off?
