No power on hills - The 1947 - Present Chevrolet & GMC Truck Message Board Network

'72 C20 with BBC and TH350. Last spring I removed the propane system installed in the early 80s and replaced the entire fuel system and installed a refurbed Q-Jet. Idles well but runs very rich and struggles to make it up hills. I thought the timing might've been adjusted for running on propane and found it was quite advanced. Once adjusted correctly it doesn't seem to be running as rich but I still have no power on hills. Any ideas?
