HERE IS A CHECK LIST OF THINGS YOU SHOULD KEEP IN MIND
IF THE PROBLEM DISCRIBED IN THIS THREAD DOESN"T APPLY.
Check for Vacuum leaks
- Intake Manifold Gasket
- Vacuum lines
- Carburetor Gaskets
- PCV Valve
Check your oil system
- Oil / Oil Level
- Oil Filter
Check the coolant system
- Radiator Fluid Level
- Fans / Thermoswitch
- Check your engine temperature
- Does the engine heat up to normal operating temp?
- Does the engine overheat?
- Ground Wires ( Battery / thermostat / radiator support )
- Cap / Rotor
- Ignition Timing
- A/F Mixture
- Float level
- Fuel Filters
Check Idle Speed ( Cold / Warm )
- What is your idle speed when cold in gear and in neutral?
- What is your idle speed when the car has warmed up all
the way and you have driven for 10 mins, in gear and neutral?
Also Check the fuel solenoid at the back of the carb, it could cause idle problems if fit doesn't work.
Check the carb venturi's since no fuel will cause the car to die.
A loose booster venturi will cause problems when trying to accelerate, and while driving, you can use the process below to check for a loose booster venturi.
THE BOOSTER SHOULD NOT MOVE AT ALL, IF IT MOVES WITH FAIR RESISTANCE IT MAY OR MAY NOT BE A PROBLEM... BUT IF IT"S VERY LOOSE THEN IT MUST BE TIGHTENED
To check if its a loose booster venturi remove the carb lid and the brass metal screen.
the 2 arrows point to the 10mm nuts securing the screen.
with your finger try to wiggle the booster venturi's inside the barrels. The booster venturi's look like this: (yellow arrows in pic below)
If any of the booster venturi's are loose then hope it's just the secondary booster because the primary booster venturi screw is very difficult to get to.
here are arrows showing where the 2 screws are located:
here you go, primary left / secondary right:
- Yes the screws hold the venturis in
- The problem with the primary screw is, the choke and fast idle unloader are in the way... and to remove it from the carb you will have to drill the rivets out to gain access to one of the screws.
Check the booster venturies.
You'll have to remove the gold screen thats inside the air box and stick your finger in both of the barrels and then check to see if the booster venturies are loose. If they can slide in any direction or wobble even slightly they could be causing problems.
I'm holding one of the screws that secure the booster venturi with my finger... in the top right of the pic I added a close up of the booster and screw.
The screw I'm holding is for the Secondary barrel.
The top hat of the carb is in the bottom of the pic, I removed it for clarity.
If the venturi didn't fix your problem
Check PCV valve
Check for Vacuum Leaks
Check coolant level
Check the fuel filters.
Check engine oil just in case
