Throttle linkage for a 235

[Jack Guzman]

The 235 in my 51 chevy 1300 was transplanted from a mystery vehicle by the previous owner. I'm guessing they never got it running well because the linkage,as it is, doesn't work right. There is one long bent rod coming from the pedal to a pivot point on the engine.From there another rod goes to the throttle lever on the carb.This other rod has a small bracket attached to it with a hole in it for the return spring. This needs to be pulled straight down to work.I attached the spring to an obvious looking spot but it didn't pull down on the spring it tended to pull it back toward the firewall and the throttle doesn't return all the way.All there is below this point to attach a spring to is the edge of the oil pan. Anybody got any ideas to help me set this up so it works?---Jack
