Hey if anyone wants to convert to a good quality two barrel carburetor this is what i did for my jeep. I created instructions and a parts list for the conversion. Feel free to reach out to me with questions and/or further information. EDIT: MORE INFORMATION AND UPDATES IN THE COMMENTS!
230 tornado, weber 38/38 conversion.
Parts:
Two barrel intake + nessisary parts(intake gasket, harware, and nessisary parts for the thermostat)
Motorcraft to weber carburetor adapter, you may need the gaskets
99044.015
Weber carburetor: #18930.086 / #18930.020 ~
~(I used the type 38 DGMS #18930.086 so if you use the other option #18930.020 you will need to figure out the 12v set up for electric choke. These instructions will work for both, just ignore the parts involving choke)
Weber to Suzuki Samurai air filter adapter #99010.600 (this is if you plan to use the hood mounted air filter)
Retain the old chamfered air filter gasket
Linkage kit parts for weber carburetor
#99007.116
1-5psi fuel pressure regulator, i used holley brand #12-804
7 mm spacer for weber carburetor
Paper or cork gaskets for weber 38/38
Nessisary length hoses 5/16 is what i used. Sorry i didn't write down how much i used.
May need new/longer choke cable if you decide to not use the electric choke version
Adequate length 5/16" hoses
M6x1.0 4 inch stud and harware.
If not all ready installed you will need the hood mount canister air filter and the parts that accompany the kit. The zone containes a parts list you will not need the parts for the governor. This conversion does not provide for the stock carb mounted air filter, if you do not want to use the hood mounted air filter there are plenty of universal options to choose from
Please note I probably did not call out small parts and fittings because i dont remember what ones I got/needed.
Drain engine block of coolant, Remove old carburetor and intake, retain everything nessisary for the remounting of new intake, I replaced my studs and hardware on mine but you may not need to. You will be reusing your old throttle cable if you want to, at this time i have not attempted to changed to a universal throttle cable.
*note: not every two barrel intake is 100% the same, you may need to drill and tap new ports for the crank pvc and thermostat sending unit*
Install new intake gasket and install two barrel intake and torque to spec. Refer to TM for specs.
Install the adapters gasket and adapter plate in correct orientation there is no torque spec so "tight"
Make sure you have the correct throttle connection plate on your carburetor to connect stock cable. If you are reusing the original cable like I did you will need to drill out the cable bracket hole to fit.
Cap off all the vacuum ports on the carburetor if you decide to not use them. You will need to drill a hole in the air filter horn inline to the stud hole on the adapter, if you are not confident with drilling a hole true and centered, my local machine shop charged me $30 to due it for me. Install carburetor onto intake. Install the air filter adapter onto the carburetor using supplied harware, and then the air horn using the 4 in. stud. The air horn will fit and you should be able to use the old gasket. DO NOT OVER TIGHTEN THE STUD. The stud will break the adapter, tighten enough to not be able move the air horn is tight enough. Edit: The original Air Duct for the carburetor air horn to the air filter May not work. The original duct was too stiff and un flexable for the adaper and i kept breaking them. Mine was NOS so if you have an old broke in one it may work better. The new carb sit more forward then the old stock one and the angle is to much for it to bend. I went to my local Napa and got a generic 3 inch air duct hose, about 2 feet worth. And replaced it. Now its thin and easy to pop a hole in but works great so far untill a new alternative pops up
Install fuel filter regulator someplace where its not in the way, I chose the inner fender below the horn and harness. The low psi Holley regulator has two out ports I used one to install a fuel pressure Guage and the other was the out to the carb.
You will need to orient the hoses and cables to fit but they will fit. Tune the weber to work. You May need to rejet your carb for your application. So far I will need to rejet the 18930.086 carbs idle jets similar to what is in the 18930.020. For any tuning or other resources the 232/258 AMC Jeep motors has the most support.
I did not have a canister style filter so I bought a NOS kit from saturn surplus.
The reason i decided to go this route was because i was faced with a problem that was slowly growing bigger; first being that i had to special order my old style air filter element because none of my local auto parts stores had any instock, napa, carquest, O'Reillys, autozone. Then i started rebuilding my carburetor and a quality kit was $60 and that wasnt bad but my carb was cracked in the bowl and i decided it wasnt worth doing twice. I wanted to retain as much of the originalness of my truck as i could. The Motorcraft 2100 is a good carb but you cant get a new one any more, only the knock offs and rebuilds, and the Holley 2 barrels was also a good option but Holleys are designed for "faster" applications, which this Jeep and motor is not even in the same solar system. That didnt leave alot of options, Redline Weber was, and still is, a well known carburetor known for their ability to proform well on road and off road, still with oem support and straight forward design that allowed for vast modification to work with our engine and application, made this a great candidate for my idea. I had a 32/36 on my old postal jeep and it was a night and day difference.
I decided screw it and do it. Searching on the various groups and the Zone, even the old forums, I didnt find anything directly helpful with what i wanted. I wanted to keep as much of the military aspect and originally as possible. So far it work. If anyone has any questions or needs further information or clarification feel free to ask! Also I'm tossing around ideas for a a 32/36 conversion using the original one barrel intake if any one would like to help.
