Kevin - Excellent! That would be very helpful.

Dave - I think that thing is an idle solenoid. Some were used to bring the idle up when the air conditioning was running, and some were used as anti-dieseling devices. Not sure which yours is, but someone will tell you, soon.

 

Maybe would explain why it's nonfunctional. Neither applies to my truck.

From what I'm reading and seeing I think it's a YFA. Planning to watch this hour long rebuild video youtube and fall asleep. Thanks for all the help today guys.

Back at it tomorrow

 

Night, Dave. (The correct response is "Night, Chet".)

 

And here I was thinking you sang on Diamond Ring.

 

Let's set the record straight, it is/was This Diamond Ring. Been wondering how to incorporate something about that in my sig.

 

HAha yessir, too lazy to type the article on my phone. Maybe something like "this diamond ring doesn't sound like a ford"

For anyone that may stumble across this thread in a search, I came across a great video. Doddering old man, but good visual reference and shows some things like accel. pump in action:
Carter YFA Carburetor Rebuild Part 1 of 4 - YouTube

 

Got into the carb. Was cleaner than I expected. But when I took the float and jet out there was some yellow fuel and trash stuck in there. Metering rod was terribly out of adjustment. Check weight and idle screws were dirty, but no grooves or wear.

Finally found a number under all of the good: 7308 S. Of course last night I picked up 2/3 kits. I need #3 hahahah. I did notice the throttle body was pretty gummed up, stuck when it was closed. And something Charlie mentioned: I noticed during no-start that the choke was out. Carb probably could have slipped my pinky underneath it was so loose.

Hopefully I can figure out what I'm doing and get her back together.

 

351HO and 460s were carbureted through the 1987 model year. 1988 up were EFI. On the 460, there are some detail changes in the 1989-90 timeframe, the fuel lines moved to the back of the engine in 1990 when the frame mounted pump and low pressure in-tank pumps were replaced with the high pressure in-tank pumps. The 1988 and 89 460s had an external air to oil cooler, in either late 89 or in 1990 it was changed to the problematic water to oil cooler.

 

Dave, I'll move the carb comments to here. The two idle solenoids are: front is AC idle up, rear is your anti-dieseling one. The dashpot suggests it may be a carburetor for an automatic originally. See if you can get a good idle adjustment with it unplugged (if it works) and then bring the carb idle screw down to around 550-600rpm. With the solenoid connected adjust it to bring the idle up around 650-675.

 

Will do once I get it running long enough to do that. So I can just leave the front off. And what's the failure rate on the A-D? It's rusty and sticky, yet to see it contact the cam/choke/ wherever it meets.

 

If it will move in, it should be slow going in, back out should be a lot faster. The whole dashpot section moves with the solenoid.

 

No more updates tonight. Raining pretty well and I won't leave class until 11. Did grab a couple pictures today. One just to play around with photoshop grille colors. The other is the animal tracks I was talking about. Think this means it sat?

 

Raccoon, maybe? Hahaha.

 

What I'm thinking. Height of the hood would have given them a nice access to the back yard. Plus plenty of water standing in the bed for them to drink.

 

Well, found an accel coil in stock locally and put that in today. Truck was running like a dream for about a half hour, longest I've had it running. Had the idle settled down to just under 1k and smooth. Surging a little, but not shaking the truck or anything. Had to restart a few times, fired right up.

Turn the truck off to get carb cleaner and start looking for vac leaks. Had to answer a phone call. Based on the timer on my phone I was gone 4min 38sec. Truck wouldn't start. Check choke, idle screws, mix, voltage, anything I can think of. Now that the carb is rebuilt it's definitely getting fuel. Steaming, so I'd assume flooded. Let the truck sit about 30 mins, still no start.

At this point I have three suspects. The 5 day old TFI was killed by a bad coil? Or the cap/rotor, or the EGR. Took the cap off and the points inside are old and dirty. Took the egr off after about an hour of sitting and still got steam out of the left side vent. Covered in black soot, some goo came out, compressing it by hand it sounds sticky inside.

Here's a few pics for y'all. Would a worn rotor cause stalling/no start when warm ?
