[AT] OT - JD STX38 fuel problems

[Vaughn Miller]

It would have nothing to do with the poor fuel flow he witnessed at the
filter.  It does nothing to regulate flow into the carburetor bowl either. 
As I said, it will close off the main jet (to prevent backfire), so it can
of course prevent the mower from running.

Seems to me it has everything to do with fuel flow if it is not working
properly. If the wiring is intermittent or the coil in the solenoid has
some
windings that short out it may not be opening properly or staying open
properly during run time. It appears to be opened by turning on the switch
and is supposed to stay open until the switch is turned off. If it isn't
opening properly or is intermittent it would explain the symptoms
present..
It may start acting up only after running for awhile as it heats up.

The solenoid at the Carburetor bowl shuts off fuel to the main jet to
prevent backfire, and will have nothing to do with the flow into the
carburetor.

4.) What does the solenoid do in the carburetor bowl? Does this just let
fuel flow when the switch is on? Doesn't look like a pump. Is this
solenoid
acting up? Wiring loose or corroded? This may be where the problem is. Is
the carburetor bowl clean inside?
