I have a ST G15 control line glow engine with the square venturi that will start and run if I prime it from my squirt bottle but will not suck fuel from the fuel tank.
The tank and location works with two other engines so I know the problem is with the G15.
I have checked the spraybar and it is not obstructed.
And I've tried using an initial needle setting of 1 1/2 turns out to 3 turns but the engine does not respond.
Can anyone help with this problem?
