I have a 1980 toyota pick up with a 20r. The truck ran ok but my buddy convinced me that i needed to rebuild the carb... Not proficient at that...So I got a new stock carb... thinking it would be less hassle than swapping in a Weber... not so, the I marked the vacuum lines when I took it apart but then the cold weather set in and I didn't work on the rig for a month. The truck will start and run until it warms up, once it is warm it will die, probably after like three minutes. I'm thinking I didn't hook the vacuum lines up right, and the diagram on the hood is ****, and haynes and chilton only go back to 83. Does anyone have a diagram for a 80 20R?
