Do I Rebuild or Replace the Carb?

Dec 4, 2002
It's to be expected since I've been building this '78 FJ40 for a year that the carb would gunk up. It was setting for 6 months before I drug it out of my brother's yard.
After the motor rebuild she ran well for about 15 miles then she spit and sputtered like crazy.
Get this! Someone retro-fitted a Motorcraft 2 BBL carb on this 2F motor. I think it's the same carb as on the Ford In-line 6 truck motor. So should I rebuild...never rebuilt a carb before but I have all the tools,air compressor,etc. It was converted to Manual choke.
I'm probably rated a 3-wrench mechanic. I've done brake jobs,replaced power brake boosters,changed cluthces,replaced valve lifters,etc.....but only REPLACED a carb,not rebuilt one.
If a mechanic charges me $50 an hour plus parts I may be close to a price for a new carb.
What's your advice? ???

Sort of comes down to preference. If you want to build your ride back up and come out of the garage with the new a new one. Sell your old one to one of these guys who has experience with rebuilds.

OR....if you feel like learning something, rebuild it. If you're not in a hurry, rebuild it and use it. If you're ready to roll, buy a new one, rebuild it, and sell it rebuilt or keep it as a spare. like me...try to rebuild it, do piss poor the first time and buy a new one and re-rebuild your rebuild.

I love the Aisin carb. If I were you I might be inclined to buy a new Aisin to replace the retrofitted Ford one. If you had an Aisin, I would rebuild it.

I will admit right up front that I am biased.

You need the stock Aisin. Weather new or a salvaged rebuild, it needs to be what came with the 2f. If you find a salvaged carb a rebuild kit is $30 or so. Follow the tech manual and take your time, (youcandoit).
