Default C2 1964 carbureted, cranks, has gas, has spark, has compression, won’t start

I have rebuilt the carb, replaced the plug wires, plugs, distributor, ignition coil, battery, and I have spark, gas and compression but it won’t start.

For it to start, all of that gas and spark has to happen at the right time. You rebuilt the distributor, which means you must've removed it. Did you get it back in right? Or is it 180* out -- pointing at #6 when #1 is at TDC and wanting to fire?

it’s pointing at #1 while its at TDC

Is the rotor at #1 on the compression stroke.

Does it do anything when you spin it - cough, sputter or just spin? Sounds like distributor could be 180 degrees out if you turned the engine with the distributor out. I would also double check all the connections to the coil, distributor, point gap, etc. Don't have a rotor sitting around somewhere on your work bench do you? I only ask because anymore that's probably something I would manage to do.

The correct question...
How did you check for spark ? Eg -- make sure the points are opening properly...

remove the driver side valve cover, turn engine until both #1 valves are CLOSED, and #1 pison is @ TDC.................at this point, the rotor should be pointing to #1 electrode.

If you know what you're doing, you don't have to check #1 valves..............you'll feel compression out the spark plug hole on the upstroke and will know that the piston is at the top of the compression stroke.

All it does is crank, no sounds or anything

I did set the point gap, and then I checked for spark at the plugs

#1 is at TDC on the compression stroke... AND on the exhaust stroke.

Be sure you set the distributor with #1 on the compression stroke, as others have mentioned.

That's where the phrase 180* out comes from...

The firing order is


1 8 4 3 6 5 7 2

how many of us first-time engine builders have installed the timing chain with both dots facing each other and then installed the distributor with the rotor pointing at #1 terminal?
Dave Vizard's book helped me greatly, but it didn't keep me out of trouble on this critical difference-- valve timing vs ignition timing...

So it sounds like you checked and you do have spark when you spin it.

Did you turn the engine at all while the distributor was out?

You rebuilt the carb so that is a place I would look since you aren't getting any hitting at all when trying to start. It may take a while to fill the carb up by the fuel pump. Did you try to fill the fuel bowl by priming or just priming down the carb throat? Have you worked the throttle while looking down the carb throat to see if any fuel is being squirted by the accelerator pump?

I did not turn the engine while the distributor was out, and I did try priming by pouring down the carb throat. I have a stupid question for you. What part of the rotor is supposed to be pointing at #1?

The conductor end. The yellow end. The brass end. The end with the little shiny tip on it. The end that is flat, yellow, and will shock you if you hold it while cranking the engine.

My gut tells me it's out of time....time to verify the distributor is indeed in correctly, and the firing order is correct on the cap. This is a very common occurrence.

I verified that the firing order is correct on the cap, and that the rotor is pointing at #1 while it’s at TDC

And just to make sure: as others have said, have you made sure the #1 piston is at TDC on the compression stroke? Remember, it gets to TDC with every turn of the crank, but only gets to TDC on the compression stroke every other turn of the crank.

Get notified of new replies

To C2 1964 carbureted, cranks, has gas, has spark, has compression, won’t start

yes it is on the compression stroke

Well, since there is spark at the plugs, it is static-timed to TDC on the compression stroke of number one cylinder, try squirting some carb cleaner or gas down the carb and cranking it over. It will start right up, since it has spark at the right time and place, and compression. Your fuel pump might be connected wrong or inoperative. An engine cannot NOT run with compression, fuel, and ignition, all in the right timing sequence.

One thing to think about, if you dumped fuel down the carburetor throat the spark plugs could just be very wet with fuel and will not allow a spark to jump the gap until they are cleaned.

Pull a plug and have a look, what ever you do don't put your face over the carburetor while cranking the engine just in case it spits back plus get a fire extinguisher for safety.
