Just bought a 71 AN600. drove it home (40+ miles freeway/streets) no
problems. Drove it around town many times and also had no problems.
Then after about 15 mins (5 on the freeway) the engine starting cutting
out. It lost all power, and extremely difficult to keep running. Was
able to nurse it almost home before it quit completly. After 20 mins
broke down, I tried to start it, and it ran fine. Since then I have
experienced no problems on many short trips. Then it happened again
(on a short trip this time). Pulled over, waited a minute to restart,
and it ran fine. Not sure if this is a common problem or an easy fix.
I imagine its a fuel or a timing issue. The fact that its intermittent
puzzles me. Tank is full. Where should I look first? Appreciate all
suggestions - thank you.

intermittent engine cuts off
Re: intermittent engine cuts off
When i bought my Green car the guy told me he rebuilt the mortor and
cleaned the gas tank and all lines. So when that happened to me i
that was the one place i did not check, but to find out the motor was
not rebuilt and the gas tank was not cleaned and filter was pluged.
so i clean everything but still did not start untill i took the tiny
filter out of the carb, it was so bad that it would not allow any
gas anymore to go into the carb... at first when i bought it, it did
the same as or car. The motor would use up the gas faster than it
could get it.. let it set for a while than would run...
Check your gas line and filters---
Hope that helps.

Re: intermittent engine cuts off
When I first started reading your msg, I thought you had an old style carb and the diaphragm had developed a tear. Since the problem seems to show up intermittently, I am suspecting a fuel or electrical problem. And I am leaning more toward electrical since the problem goes away in an instant. Some things to try:
1) disconnect the fuel line at the carb and pump some gas into a clear container (e.g. glass jar). Does the gas look clean? You will need to turn the starter switch to the run position for the fuel pump to pump gas.
2) on the driver side of the card is a fuel cut-off solenoid.
Disconnect it (attached with one screw). It should have an o-ring on it as you remove it. With the igniton off, the solenoid rod should be out. With the ignition switch on, the solenoid should retract.
Verify the wiring (one to ground and one wire to the harness) are connected properly.
3) I suspect the problem is in the electrical and if it is not the fuel cut-off solenoid it may be in the area of the spark plugs. One bad spark plug (or one plug not receiving high voltage) can cause the problems you describe. When the problem occurs, you could shut down and remove both plugs. If one appears to be wet and unfired recently, your problem is on that side. Checking the high voltage wiring which runs between the coil and the plugs. If you have cracks in the wiring, it could be arcing to the frame and this would cause the problems you experience. Check closely the wiring to the driver side plug which runs under the metal framing for the hood area. Also, check the connectors at the end of the spark plug wires which connect to the plugs.
Also, check your spark plugs. Are they clean at the insulators (on the inside and outside of the plug)? Also, check where the coil is bolted to the engine framing....is it a clean connection or rusty. Check the wiring from the distributor to the coil....anything loose? Where the coil wire connects to the points (usually a blue wire), is the connection clean and no frayed wires hanging in space?
From the description of your problem, I am suspecting an intermittent electrical problem. And I think it is in the area of the coil / spark plugs since everything is fine, a problem happens, you start the engine and it is fine again for a while. I think something is arcing and once it starts arcing, the problem occurs. When you restart the car the arcing may not occur immediately.
good luck,
Dale
PS when the problem occurs, are you experiencing any electrical problems (e.g. radio stops working, lights dim, fan motor does not run)?

Re: intermittent engine cuts off
Something else to check......is there anything in the engine compartment which can be sucked into the air horn (air cleaner) which might be impede the air flow? The air cleaner on later models had a winter/summer switch (a flapper valve). The summer position is straight through and the winter position was air warmed by the heat exchanger (and on older cars, air heated by the engine and caught at the fan housing).
Ensure all these passages are free to flow air and are not being blocked.
good luck,
Dale
