Carb. issue....need help.

[70 StangMan]

O.K.  .... this is where the pcv hose from the valve cover is connected (along with a tranny connection I think) Is there any reason that this is a bad connection point  ?? Does the tranny interfere with it ?? I almost bought a carb. spacer with a input today but still tinkering. When I got home I disconected the set up you see and capped off the intake input and tried to start. I pumped the gas a few times and turned the key and no start.. just turned over.
Then closed the choke plate on the carb. from about a 1/4" open to almost closed and it started. My problem all along ?? Really don't need to spend $40.00 on a spacer if this set-up is alright. What say you ??

I still do ot like that PCV setup. It does provide an air supply to those runners with no compensation for more fuel Run it to the air cleaner base inside the filter area.

As for the choke, yes, it could be an issue. Get everything set proper on the carb....by the book...and see what happens.

I went to get a assembly for the air cleaner/ pcv and the "old guy" at the parts house said that air cleaner inlet is not for the pcv but for the clean air from the other valve cover ??  He said pcv left side to the intake and clean air draw right side to the air cleaner base to complete the cycle ??

[AzPete]

Yes....you can also use a filtered cap on the drivers side for intake of air. I have seen them both ways. The best for the PCV is the base of the carb......

I have seen one car have transmission issues with the PCV hooked to the same location as the tranny vac. line. Moved it to the carb base and it shifted again.

I guess older 2100's had a pcv hookup. Sent you a pm about a guy to contact...

This is the forum I sent you the  email contact from... http://www.network54.com/Forum/88781/

Thank's Pete....I sent him a E-mail.

Unless it was 90*+ there today, your choke should not be 1/4 open before starting. Adjust to the rich side, then make sure the pull off opens it up the correct amount when starting.

I did before doing what I did. 4V seems to be the common one. But I might want to keep looking. Maybe cap off the inlet and see if it makes a difference I'm thinking.

I have an OEM  1" Spacer with a PCV port, it also has an EGR Valve.  It's in great condition, I would sell it for $20.00 plus shipping.

[AzPete]

Is that a 2V spacer?

Sorry,  Yes it is a 2V spacer.

The accelerator pump should be shooting a strong stream into both throats, if you just get a spritz, it's not working. The car will not start if you pump the gas while cranking. You need to pump the gas before you start cranking. Pump it 5 times slowly and hit the key. If there is gas in the bowl and the accel pump is working properly it will fire.

The PCV line needs to go to the manifold side of the carb, either the manifold or carb plate. The only PCV line that goes to the air cleaner is the fresh air line where filtered air gets pulled into the engine through the left-side oil cap.

I've never seen one with a EGR valve...do you have a picture ??

[AzPete]

You should be able to plug it pretty easy.....or maybe not after checking on line pics.......hmmmm.

Yea......kinda wondering myself.

Sorry for the delay, I was out of town........

That is kinda what's confusing me. When I bolted on this one it fired right up and ran but now it won't. I did run the pcv hose to a inlet on the intake that was capped off. (the other used to go into the base of the old carb but this one has no input). I'm wondering if that screwed things up. That is the only thing different that I can think of.

Yes hooking the pvc to the intake is whats causing your start up trouble.
Loss of vac draw thru the carb when cranking with starter motor.
The spacer that has the egr port mount is for 74 and newer IIRC, thats when smog came from factory.
You need a carb with the base plate connector for the pvc hook up or a spacerplate with it.
Blocking off the port for egr is possiable but looks bad imho.

[jmbour66]

The spacer pictured is actually from my 73 302.  I've always assumed that Ford was getting ready for the regulations of 74.

Thank's for the offer jmbour66, but I think this one will fit my application better. I bought this spacer off E-bay. I think it will do the trick.

That....and a new tune to be sure all is as it should be.

Yep...that's the plan Pete.

You are welcome,  I hope it comes together for you.  These cars that we love can be a real pain!

[Fordication]

Well, what happened? Did it work?

[70 StangMan]

Well, what happened? Did it work?

Yes...I posted over in the "what did you get done today" thread ( hindsight say's I should have put it here). Mounted the spacer with the pcv inlet under the new carb. Capped off the inlet into the manifold I was using and after some thin walled hose collapse issues all is well in the garage (today)

[jmbour66]

Congrats!

[70 StangMan]

Today finally finished the correct PCV setup on the car. Went from inlet directly into carb base to a inlet into the spacer base (new carb. had no inlet) and got the 3/8" to 1/2" hose issue solved. Everything working fine (now)
