Thanks for the offer Sal. I just got the truck back from my mechanic. I was going to fiddle with it myself but all of a sudden retired life got really busy. Anyway they adjusted the choke a wee bit and it seems really good. Now I'll see Howe it goes when I leave it for a week or two as it was a reall burger to get started in those situations. Almost like the fuel was draining out of th Efteling bowl. We'll see how it goes...

As the truck sits a few days the fuel level in the carb will start to drop and the float valve(s) will open. If the fuel pump has some age and its check valves don't seal completely the fuel line up to the carb will drain down to the fuel level in the gas tank. Possibly even lower than the fuel pump? And, if the pump is a bit tired getting the fuel back up may take a couple extra moments.
You could double check the output pressure & flow of the fuel pump.

I would be surprised if you don't have to grind on it after a couple of weeks sitting. It is the nature of a carburetor. If it bothers you, you can install a flow-through electric fuel pump back near the tank to prime the carburetor after the truck sits for more than a few days.

After sitting and before trying to fire, take the ACL lid off and operate the throttle linkage to see if fuel is shot into the carb. No fuel means either fuel bowl heat percolation and/or fuel evaporation has emptied the fuel bowl(s).

Also, a mechanical fuel pump will not hold line pressure over time. The fuel in the pump to carb line drains back to the tank and the pump may take a while to prime. Same as starting an engine having to either prime the fuel bowls and/or having to dribble a little fuel into the carb throat making the engine catch enough to allow the pump to prime itself.

Good idea, will do. Truck running fine now though I think the idle speed setting is a tiny bit too high.

Well to be honest I took it back to the shop and let them do it. After all I was way to busy at the time and I paid them to install and adjust. They said they just adjusted it and that's fine with me!

Thumbs up Re: 351 Driving Me a Little Nuts

That's OK. Sounds like a simple choke adjustment.

I could tell you a story on what I did to my 351 W. but you couldn't get it inspected and the dealer I sold it to was really P.Oed when he found out the parts were aat my EX-wifws house. Don't know why he just didn't go get them. LOL Al

I am the original owner of my 1986 F-250 with 351 engine. It always starts quickly even after setting a month. It runs perfectly in cool weather and in winter cold weather. It has severe hesitation and almost stalls when driving in warm weather. My mechanic rebuilt the original carburetor which is still on the truck, but there was no change. As i remember there was a recall when the truck was new regarding the intake manifold, and the recall was performed by the selling dealer. As my only need for the truck is in the summer I am fed up with its hesitation antics. Recently it hesitated and then quit entirely while driving. AAA flatbedded it to my mechanic who found the problem was unrelated to the hesitation and was rodent eating the gas line near the top of the forward tank (it has dual tanks). I was quoted $800 for a new carburetor but I need the truck so seldom it is going to leave home, asking $650.

Barnstuf, if your interested, I have two NOS Holley four barrel carbs for an '86 Ford truck with a 351W engine. Holley number is E6HE-9510-AC. Holley number LIST 50305-2. You can have for a heck of a lot cheaper than the $800 one you mentioned.
