73 C-50 questions

[3v0]

I bought the thing to move from CO to OK about 20 years ago. Have been using it for storage since then.
It was way underpowered in spite of having a Mr GoodWrench 350. Had one really bad run loaded into the wind for 100 miles where it would not go over 40. Changed the fuel filter. No help.
Last time I started it I disconnected the rubber fuel line from the metal line coming out of the carb. It was crimped maybe flowing about 1/2 the fuel. Facepalm!
Never occured to me to check the work of the guy who put in the engine.
Caveat emptor!
