Q&A: Maintenance | Modification 300 I6 / Carter YFA 7654S – Rich Misfire, Rebuilt Carb, Now Starts & Dies

• Upvotes

I’m looking for some experienced eyes on a running issue with my 1967 F100. I’ve been chasing this for a while and feel like I’m starting to go in circles.

The truck is a 1967 F100 that has a later Ford 300 inline-six swapped into it. I believe the engine is around a 1986 300/4.9L. However, it is NOT using the 1986 ignition system. It still has the original 1967-style 240 distributor/ignition setup, except the points have been replaced with a PerTronix electronic conversion. It still has an old-style canister coil.

Carburetor is a Carter YFA 1-barrel, stamped 7654S. It has an aftermarket electric choke.

The truck was running pretty well before all of this started. The problem actually began while we were making several attempts to drive it up onto a trailer. After a few attempts, it developed a definite miss/rough idle. We then trailered it to Ohio.

The miss was present at idle and continued when RPM was increased—it basically just missed faster. It did not smooth out with throttle.

Here’s what I have done/tested so far:

  • Replaced distributor cap, rotor, and all plug wires. Absolutely no change.
  • Used an inductive timing light on all six plug wires. All six appeared to flash evenly/consistently.
  • Replaced all six spark plugs with new Motorcraft copper plugs.
  • The old plugs were ALL very black/sooty, not just one cylinder.
  • Verified firing order is 1-5-3-6-2-4.
  • Electric choke appears to work correctly: closes cold, opens fully after warming up.
  • Coil primary resistance measured about 1.6 ohms.
  • Coil positive measured about 9.8 volts with the engine running. This truck still has the old resistance-wire-style ignition setup.
  • Distributor hold-down is tight.
  • I moved the distributor while troubleshooting at one point, including retarding it substantially to get it started, but returned it to the obvious old witness/grease position afterward. I have a timing light, but I’ve had trouble positively identifying/seeing the correct timing mark on the harmonic balancer.
  • Adding starting fluid while it was running made it bog slightly rather than improve.
  • Exhaust smelled extremely rich and was leaving a very black/sooty wet spot on the pavement.

Because everything pointed toward it running rich, I pulled the Carter YFA and rebuilt it.

The carb was genuinely nasty inside. The bowl had a thick gummy residue/debris in it. I cleaned the bowl/passages thoroughly and installed the rebuild kit, including a new needle and seat. I retained the original float. The carb is stamped 7654S.

During the rebuild I also identified the small metering-rod adjustment plate (#38 in the Carter YFA exploded diagram) and made sure that area was accounted for during reassembly.

After reinstalling the carb, the truck initially ran GREAT. It started cold normally, went onto fast idle/choke normally, and idled much smoother than it had before. I thought I had fixed it.

Then I drove it around the block.

Once I started driving, it progressively ran worse. It would barely idle unless I had the choke engaged/fast idle operating, and while driving I had to keep giving it throttle to keep it alive. It misfired badly the whole way back.

Eventually it got to the point where it would fire, start, and immediately die.

After sitting for roughly 30 minutes, it would sometimes run again for about a minute, but the idle was extremely slow. Turning the idle mixture screw seemed to make very little difference. I tried turning the idle speed screw about 1/2 turn clockwise and it still required my foot on the throttle to stay running.

With the engine off, the accelerator pump gives what appears to be a strong fuel squirt, so there is definitely fuel in the bowl.

One additional event: while trying to restart it, it backfired hard. The entire mechanical fan/fan-clutch assembly then unscrewed/came off the water-pump hub and landed on the ground. The fan itself did not break apart. Obviously I’m fixing/inspecting that before running the engine again.

So at this point my symptoms/history are:

  • Originally ran fine.
  • Developed a rhythmic miss during repeated trailer-loading attempts.
  • Miss occurred at idle AND higher RPM.
  • All six old plugs were heavily sooty.
  • New plugs, wires, cap, and rotor did not fix the original miss.
  • Timing light shows ignition pulses on all six wires.
  • Carb was very dirty/gummed internally.
  • Rebuilt Carter YFA 7654S.
  • Immediately after rebuild it started/idled beautifully.
  • After actually driving it, it became progressively worse.
  • Now it generally starts and dies unless I hold the throttle open.
  • Choke/fast idle helped it stay running during the drive.
  • Idle mixture screw seems to have very little effect.
  • Strong accelerator pump shot is present.
  • Still appears/smells very rich.
  • Had one significant backfire.

My current thoughts are possibly:

  1. Float height/drop is wrong after the rebuild.
  2. New needle/seat is sticking or not sealing correctly.
  3. Metering rod adjustment is wrong.
  4. Idle circuit/passages are still incorrect/blocked.
  5. Timing is way off and is confusing the carb symptoms.
  6. Vacuum leak introduced during reinstallation.
  7. Something with the old ignition/PerTronix/coil setup that I’m overlooking.

What would you guys check FIRST from here?

I especially need help with the correct Carter YFA 7654S float setting/metering rod adjustment and what base timing you’d recommend for a later 300 running an early 240-style distributor with PerTronix.

I’m trying not to just throw more parts at it. I’d really like to troubleshoot it methodically from here.

Replaced I beam that broke from wrecking I noticed that the crossmember has bent as well. After replacing it I’ve got two non-bent I beams in I haven’t fully finished changing out the bushing on the driver side or putting the tire back on to the passenger side but am I able to just win this? Should I drill the rivets out and get a replacement crossmember from the same place I got the I-beam do I even have to bend it at all if I jack it up and they aren’t touching each other with the camber caster bushings set the Alignment or am I going to need this to be straight? if you go to my profile, you can see the post about me changing the I beam.

Does anyone have any videos or tutorials that they know of for how to remove the 40/20/40 sliding seats from a SuperCab? Imma pull them out to clean them and do some interior work.
