That makes sense, Joe. Pump has screws around the middle. I'll try hooking up the regulator again, and use permatex on the fittings, as teflon tape was not sealing well. Engine runs great, but does blow alot of black on my driveway on cold startup,(exhaust pipes point down). I don't have the choke hooked up and usually give the accelerator a couple of pumps in the morning, and the big Poncho starts right up and idles nice.
