Engine shuts off when driving?

Hey JOH,

The first things to check in this instance would be the spark plug condition and gaps.

Have the spark plugs been replaced recently?

I have attached instructions below on how to remove the spark plugs and it also shows specs for the gaps.

If not recently replaced I would advise starting by changing out the old spark plugs.

The next items to check will be the air filter and fuel filter.

I have attached the procedure for replacing the fuel filter, if this has not been recently replaced please also replace this and retest.

The engine air filter I do not have replacement instructions for but it should be easy to identify in a plastic air filter box at the end of the air intake ducting. Check and replace this if dirty.

I would also replace the ignition wires, distributor cap and rotor if not recently replaced also.

Once all of the service items are up to date see what you get with the running fault.

Regards, Joe

Hey JOH,

Yes i see it is a carburetor vehicle from the information i have here.

Was there any work carried out before this fault occurred?
Does it rev up okay in park?
Is the problem only under load when accelerating?

Can you please check for vacuum leaks?

Guide below to check for leaks.

Since you have a carburetor on this vehicle you will want to check around the base of the carburetor, the intake gasket and everything that is fed a vacuum supply from the intake.

Please check condition of all vacuum hoses and replace if deteriorated.

I would say after that the next step would be to further test for a restriction in the fuel system.

Please check for vacuum leaks and let us know what you find.

Regards, Joe

Click above link for more information on how to go about.

When the top do not move while the crankshaft is being turned, the timing belt is bad. Push at the belt to check for deflection and if it has a lot of slack, the belt has stripped a few tooth.

You would need to remove the crank pulley and lower cover to replace the belt.

Diagram shows the timing marks.

Yes, you would have to do that.

Yes, you can use the bolt holding the cam sprocket to turn the camshaft. Turn the vrank away from TDC by about 20 degrees first and after getting the camshaft timing correct, turn the crank back to TDC.

Question closed.

Test the airflow meter-let me know
