Cool truck! Be patient - you're picking up the slack on some 30 years of deferred maintenence.

- Replace intake/exhaust manifold gasket, check intake for cracks under carb
- Rebuild carb with kit from CarQuest (replace secondary diaphram while you're in there)
- Clean ash/deposits from plugs, or replace them.
- Install electric fuel pump to prevent vapor locking/hard starts when hot
- Try to fix the electric carb fan - it should run for up to 30 minutes after you shut the truck off on a hot day.
- Check for other vacuum leaks, proper base timing, a functioning vacuum advance (not rusted shut or hole in diaphram).
- Expect 12+ MPG in all around driving.
