I'm going to nickname it Pringles -once you pop you can't stop! Except by pulling out the snorkel and holding your palm over it. The brown wire is connected to a black wire coming from the coil and when I tried connecting it to this second open wire coming out from somewhere else on engine, it didn't work either. I have attached the brown wire connector to the throttle slot and it won't stall.
I ended up using it's green counterpart, my Corvette to do the grass.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
