i was doing 3min cycles at 200F then BDC cooldowns, 5 times. I wanted to type as much as possible to make sure I answered all questions to get to the point . When I pinch the LSN to shut it off, it takes about 6-7 seconds to die and it speeds up before stalling so I know its rich. But having to get fuel spitting out to get any kind of fire in the engine is whats strange to me.
