Acceleration Issues. 1980 20R Please Help
« on: Nov 24, 2009, 08:18:47 PM »
Well, seems like I changed everything I could on this engine but I'm still having the same acceleration problems. Here's a list of thing's I've changed on the engine since I bought the truck:

-Spark plugs/Wires
-Weber Carb/Weber intake manifold
-Headers
-Just changed the oil
-Fuel filter
-Swaped in W56B
-New Clutch/Pressure plate
-Resurfaced flywheel
-New gear oil

The truck runs fine when I'm driving on level ground, but as soon as I hit a large enough hill when I step on the gas pedal, seems like the engine just boggs down and nearly dies out. My truck hates it when I'm not driving on level ground, even on hills with the slightest incline. Pretty much ran out of things to change on here, and any suggestions would be greatly appreciated. Also if you have had the same problem and fixed it, I would appreciate it if you let me know what was causing the problem. I'm not really proficient with mechanical vocabulary so if you could dumb it down for me that would be great. Thanks !

Fuel Pump?

Hole in fuel line (fuel pump will then suck air)

Thanks ! I think I might try tuning the carb before going out and buying a new fuel pump.
