The clicking could also be the solenoid trying to make contact after prolonged starting. When the battery dies down the solenoid doesn't get enough juice to make a solid contact and 'clicks'. I would take your batt. to the parts store and have them put a full charge on it.

Since it did start at WOT I would think you still have a fuel issue. I bet if you sprayed Ether in it it would crank up and die once it burns away.

Sounds to me like not enough fuel getting to the carb sprayers, did you ever look to see (with the engine off) if you get a good pump of fuel from the squirters in the carb?

Yeah, I am getting fuel in the carb when I move the throttle, but if I spray starting fluid in there nothing happens. Still just turns overs a bit, acts like it wants to start, and then nothing. Just the winding down (of the starter I think) sound.

A starter bendix, eh, Print Dad? I'm learning stuff existed that I'd never heard of, lol. So, if the engine is cranking, but not starting, it could be the starter bendix? The engine will crank for a bit, without starting, and THEN act like it wants to start. Then it'll just click and wind down. Does this sound like what you're talking about? I'm gonna go google it so I have half an idea what you're talking about, haha.

Hello,

No...if cranking a lot and not starting it is a different issue. A bad bendix kinda makes the motor turn just a little then you hear the whine

I am not sure if we are talking the same thing when you say it turns over but will not start.

The starter bendix is inside the front cone of the satrter. When you turn the key the bendix slides forward and engages the flywheel. It is supposed to stay forward untill you let the key go or the motor starts

When you say the motor turns then you hear a whine down that sounds like a bad bendix. Almost as if you let the key go and the motor doesn't turn. Listen to the starter does it sound like it is turning the motor and then the starter revs (liek the whine sound?)

It is not to be confused with a weak battery or a clicking selenoid.

The bendix allows the motor to turn over. It will not keep the motor from starting unless the bemdix kicks back before the motor can start.

This is hard to explain. Imagine if the starter only had a few teeth left. If you were lucky and the teeth hit the flywheel teeth, the motor would turn. If the teeth slip out of contact you would hear a whine. Of course you would then have trouble because the teeth would not engage.

In the days...we would replace the bendix and change the brushes. This can be a bit tricky if you aren't careful.

I hope this makes some sense. I will google to see if I can get a better explanation... Print Dad

Hm... let me see if I can give a detailed explanation.

If I turn the key, the motor will sound like it is turning - the normal sound you would expect to hear when starting a car. The only difference is... the car will not fire and start. Now... sometimes after a second and sometimes after a a long time (and sometimes not at all because I stop turning the key before it happens) the car will make what I can only attempt to describe as a starting sound - like it is tricking me. It really sounds like it is going to start - just a quick pop or something. Then... the starter will make a little "click" and make a winding down sound that I will wait for to stop before I begin cranking again.

Hello,
Lets back track a bit.

Did you replace the new coil?

You should check the spark at the plugs again.

Ypu say there is gas in the carb and you can see it?

If so, pull several plugs and see if they are wet. You can wire brush them or just replace them. (Keep the old, they will dry out if left outside)

If you have spark to the plugs and gas in the carb it should start unless here is a timing issue. I would not freak however. A new set of plugs is a pretty inexpensive purchase and may help.

As far as the starter...it sounds like the bendix is going. When this happens you can turn the motor over long enough ti fire especially with wet plugs.

I know this must be frustrating but I think you are close. If you change the plugs and it starts...I would consider changing the starter in the near future.
If th plugs are fouled and the bendix is going you won't be able to crank long enough to fire her up.

Don't give up you are close and when she starts you'll be proud...... Print Dad

Print Dad, you should be a motivational speaker, haha.

I can't see gas sitting in the carb, but if the throttle cable is pulled, I can see gas squirt in.

I did check the spark again after replacing the coil.

I'm going to try to change the plugs tonight - I pulled one this morning before class and it was sorta wet. The threads more than anything. The plugs are pretty much black, though - the tip where the spark is, anyway.

Thank you for the help so far, guys. This forum is a great resource for newbies.

Question: Should I rebuild the carb before swapping the plugs? Will it harm the plugs to attempt starting the engine a couple times if it's flooding?

Hello Mesomorphman,
Do not rebuild the carb yet. Repeat..don't do it yet.

You need to get the car started. Once you know she runs perhaps we can fix your carb. Replace the plugs and crank her over....give no gas. It sounds like the plugs are fouled and perhaps the carb is out of whack but if you start messing with the carb, you introduce another unknown issue.

I understand you must be getting anxious, but for now put in new plugs, be sure to gap them and start the car. If you crank more than 15 seconds and it doesn't start, then spray a small amount of stater fluid into the carb. Put on air cleaner and start her.

Oh yeah, you can't see the gas unless you hit the throttle. I even forget what carb but that is OK for now.
After she starts if you send me a message I will help you figure if she needs a rebuild or adjust etc.

One thing at a time. Charge the battery, install new plugs...start her up.

I am sure we will get her going....Print Dad

You're right, Print Dad. Better to do things the right way. I was getting anxious and in a hurry. I'll swap out the plugs tomorrow (may take forever - it's a tight fit in that engine bay) and then see how it goes then. Is there any way to clear the fuel out the engine if it IS flooded to start with a clean slate, so to speak?

Hello Mesomorphman,
Don't worry about the gas in the motor. By now it will have dissapaited or gone past the rings. When you go to start her, just hold the pedal to the floor. No pumping.
Repeat...No Pumping . Follow my tips on cranking and perhaps starter fluid.


Trust me we can fix this and I imagine you are anxious but we gotta do it right.

Just so I can start thinking have you mentioned the carb type and size?

I have been replying to several situations and I kinda forget.
Not a big deal. I think I'll be able to offer advice on whatever you have.

Charge the battery
Gap plugs
Change plugs

Hold pedal to the floor, crank 15 seconds.
If no start, spray starter fluid and start the car.

Trust me on this, when i was a kid, I had so many problems with my Fords.
I learned quite a bit about motors etc. I know this gets frustrating but when she is done, you'll have a great running reliable car. When she starts don't get nervouis if she is rough or anything like that. We can solve all the little stuff. Print Dad

I'm not sure about the carb. It is a Motorcraft D1VF-AA. Old looking. I attached pics.

Hello,
See the first picture? take the base plate of the carb off, this will let us see the whole carb. I am thinking it is an older autolite but can't fully see.

You will get this done. I am confident....get her running and then on the phase 2....Print dad

I will post new pics of the carb. First, though, let me just say... IT STARTED! I swapped the spark plugs... the old ones were a little wet and black... and it started right up. Almost lost some eyebrows there when it caught, though. But yeah. It started. Thank you Print Dad for bearing with me this whole time. And thanks for all the input the rest of you guys. My first project with a car and you guys helped me figure it out, even though I am a newbie. I'm going to take a break for tonight and get on the whole tuning/troubleshooting tomorrow. Right now I just wanna enjoy that sweet melodious exhaust.

Glad to see you got it running
