1976 2F Carb Options (1 Viewer)

[cvan1971man]

Looking for insight on carb options for a 1976 2F engine.

It came with a Holley 2 bbl, but have heard horror stories for that carb. Most likely won't be doing too heavy of off-road use so not worried about fuel flow for steep ascents / descents.

I know that Aisin was the OEM carb, but getting one rebuilt correct is the problem. I have also heard of others doing good with Weber carb.

Any thoughts or insights would be helpful.

ALSO, MOST OF THE AISIN CARBS THAT I AM SEEING ARE FOR 20R AND 22R ENGINES. IS ONE PREFERABLE OVER THE OTHER FOR THE 2F FJ40 ENGINE? ARE THERE ANY MODS THAT WOULD BE NEEDED FOR CHOOSING ONE OVER THE OTHER?

I run the Webber dual 38 on my 76. It has been pretty good.

Weber 38 for me on my 1976 also, no problems.

I have heard and seen asin carbs be rock solid. I recommend them. The cruiser was made to come with them.

I am using one of City Racers carburetors on my 2F and am very satisfied with its performance.

Bought my 77 with the same carb. I fiddled with it for a few of years then switched to a Webber 38 and fiddled with it for a few more years. I finally bit the bullet and decided to go back stock and started accumulating everything I would need to get the job done. Ended up with a carb from a 76 that I learned how to rebuilt and finally took the plunge. The journey was not as smooth as I would have hoped but years later I can say it was worth the effort. Once I got everything sorted out the truck has been a dependable joy to drive. I'm probably due for another carb rebuild but I'll wait until fall after it cools off first.

Going Aisin-details, details, details

I made the commitment some time ago to ditch the aftermarket carbs and get back to stock, or as near as possible. Down the torpedos with Holley and Weber. My 77 FJ40 has never had its original carb in the years I've owned it so here is what I have pulled together: 1/76 carb - just completed a...

http://Would you recommend rebuilding myself or sending off to one of the experts?

Your call, I was a complete beginner when I did mine. Made a couple of mistakes but came away with a pretty decent understanding of how these things work.

I got a cheap Chinese version off eBay and have been surprisingly satisfied with the quality and performance on my 76.

Did you have to do any tuning on this carb? Any issues? What about MPG?

 

[HoundDog]

The Chinese copies of the stock carb work good. Get them from Trollhole or City Racer. No tuning required, plug and play if you still have the stock rod linkage.

Or find an OEM Aisin and have it rebuilt, tested and tuned by Jim C or Mark at Marks offroad, both can be found on MUD.

Had to make a pin with set screw to hold the end of the choke cable and change electrical Conn for idle solenoid but that was all. No tuning. Have not driven enough to determine a mpg.

From what I see, the city racer carb is Japanese at 295$. I paid 70 w/free ship for Chinese version, which places like parts geek etc sell for 150+. I planned to try it out at least until I can get the original rebuilt.

A Motorcraft 2100 will bolt to your Holley adapter. They're simple and a dime a dozen. I've been running one on my 2F for at least 15 years.

 

[BigHighBlue]

just installed a CityRacer in my '78 and so far it runs great. It came recommended and I would recommend. Compared to the cost of an OEM its a big savings as well.

Trollhole or City Racer are both good choices - have you considered Holly Sniper? I have a Trollhole for years now and no issues, but if I was changing carbs, I would consider the sniper.
