I have a 1982 F250 with the 351w and stock 2 barrel carb that has sat for an extended period. The last time it ran was about 1 year ago. At that time the idle was very poor. Basically it stalled every time I let it idle.
Fast forward to yesterday, I went to start it and the throttle plate was frozen and there was lots of moisture in the carb & air cleaner. I eventually got the plate free, but the truck would not start. I suspect that the Carburetor needs a rebuild.
The truck is super low mileage (37K original not 137K) and totally stock. I'm not opposed to buying a new carb, but I would like it to fit like the original without modifications if possible.
What would you guys suggest? Rebuild it myself, buy a reman, or buy new?
Many will recommend rebuilding it. Much information can be found using the forum's "search" feature or online [i.e. Youtube]. I have had good luck with the rebuilt carburetors offered on Rockauto. Their carburetors are remanufactured by a Canadian company [Autoline].
I lean towards the Motorcraft 2100/2150 series carbs. Simple design and reliable with parts availability that doesn't require breaking 'ye olde piggy bank. If you choose to go with a rebuilt, be conscious of jetting.
I purchased mine from Performanceoverstock off of ebay with no core charge. It became apparent that they were a distributor for National Carburetor when the carb arrived from Florida, two cities away from where National Carb is located.
The listing shows application fitment to '81 but this is the carb i purchased for my '84 ( I catalog and bookmark every part purchased) and the jetting was a direct replacement for the original carb. It's been well over a year since the carb has been installed and it has performed like it should. A few adjustment tweeks may be required, but overall...it's a well rebuilt carb. $170... with no core return or core charge.
No fuss, no muss.

Reason: More information
If it's truly 37k miles, rebuild the carb. Lots of videos on this, it ain't hard. High mileage carbs will waller out the throttle shaft bushings and introduce vacuum leaks, these can't be tuned out and it will run like ****. They can be drilled and rebushed.
Check LIST # on carb for applications and bounce it off the one listed in the shop manual, as it will specify what the correct size carburetor is for that motor. After 30 years parts get swapped out.

I would start with replacing the hood to cowl seal so rain does not pool on the air cleaner.
(and ruin your new carburetor)
Gary Lewis has some good pictures of how we can use an inexpensive garage door weather seal to keep the engine bay dry.
Beyond that I would not shy away from rebuilding it yourself if you are organized, detail oriented and have a clean well lit area to do it.
If you decide to get a rebuilt carb *make sure* that all the linkages, brackets etc are the exact same.
If there is something the 'new' carb doesn't come with swap it over *before* returning your old carburetor for core.
(there are many tales of woe because these simple steps were not followed)
Thanks to all who replied! Particularly those who provided links to rebuilt carbs and pointing out the importance of the cowl seal. I'll be replacing that seal soon.
