Need some basic help/answers. Novarossi motor dies now when the igniter is removed. It is still on the bump box, but dies quickly after removing the igniter. Throttles up, but the clutch seems to be grabbing a bit. Air leak? Bad fuel? Replace glowplug? Or all of the above--lol
Any help appreciated--

To go further on this....
The most common reaction back is "but the plug glows fine!"
The glowing is not the main function for the ignition, it has a helping function. The glowing is needed to let go ions from the glow wire. The ions will react with the fuel to startup the ignition/combustion. When the wire is dirty from lets say a carbon build up, rust from bearings/crankshaft or other dirt from a bad airfilter then there is no good surface to let the right ions go to react with the fuel.
