The classic surge or stall on that engine on acceleration is caused by a restricted fuel strainer at the carb inlet. If it's got a stock Rochester 2-BBL carb, there will be a sintered bronze strainer about 5/8" in diameter under the big steel fitting the fuel line screws into. Remove the fuel line with a flare nut wrench, while holding the adapter with a big wrench, 1", IIRC, and remove the adapter fitting and the strainer. The strainer will be held against the inlet side of the adapter with a short coil spring. The strainer has a cone-shaped center that needs to point toward the incoming fuel. Some newer-style carbs use a pleated paper filter instead of the bronze strainer. Throw the old strainer as far as you can toward the junk pile. Install a replacement strainer, being sure to point it the right direction, remember to replace the spring, and install a new metal ring gasket between the adapter and the carb housing. Be careful not to cross-thread or strip the thread in the carb body. Tighten the adapter carefully, but firmly into the carb housing. Use a flare nut wrench to tighten the fuel line, and a 1" wrench to hold the adapter in place, and drive on!
