Slant 6 Gas Mileage

Must be towing a 10k trailer or trying to haul a tree. My / would get low 20's if I beat the crap out of it and still pull 30 on the highway.
Have to agree your cam is off a tooth, Timing is way off, Driving in 2nd gear, bad vacuum leak some where, carb is pouring fuel. bad coil not fireing the fuel, Distributor cap cross arcing inside. rotor with a hole burnt in it.
