Most likely a carb issue if you have an electric pump.

Roughly 3.5 pounds but check the carb as well.

the gas comes in rubber fuel hose into the carb. from the carb it is sprayed into the intake manifold, and then sucked into the engine through the intake valves in the cylinder head.

if the needle isn't seating properly, gas keeps dripping while the car is off, and into the cylinders. which in turn will drip into the oil past the rings. this has happened to me to the point the motor locked up due to no air space in the motor. i drained the 2.5 quarts of oil and 4-5 quarts of gas in the block, put new oil, fixed the carb, and it ran good.

you should be able to see gas dripping from one or both carbs after shutdown. another thing it could be is if you are down a cylinder, and not know it. for example, on my 1600 turbo motor, i was driving on 3 cylinders for about 3 days, and didn't know it. checked the oil, and it was higher then when i checked it before (it was leaking oil, so i always checked the oil). it was a combination of a loud exhaust, and excess power, so i really didn't notice to much, i just thougt i needed to change my plugs, or adjust the points or something, lol. anyhoo, my point is, with a loud exhaust it can be harder to tell if you are down a cylinder. and if you are gas will run past the rings and also fill up the oil. just another thing to keep in mind. good luck bro. Cool

on a plus note, you don't have to worry about sludge in the crank case. gasoline in there is great is dissolving it and cleaning it all out. lol.

Pull the carb top, check float and replace the needle valve. How is the tune up including valves?
