Re: [T3] 2-step starting
<x-flowed>JasonW=> It ultimately serves the same purpose?
No. The cutoff jet stops the piston from pulling fuel, but there are
still open air passages into the float bowl, and the carb intake is
above the float level, so even if the needle valve happens to be hanging
open, it's not possible to siphon back out of the carb.
The antisiphon valve ensures that the fuel stays in the fuel pump, ready
to go. The stock pump is above the tank, so gravity can pull fuel back
from the engine compartment.
