Carb Question? - Pirate4x4.Com : 4x4 and Off-Road Forum

jnynuke · 03-18-2005, 07:45 AM

Is anyone running a weber 32/36 on a 2F motor.I have a friend that is selling one pretty cheap so I need some information on it.I did a search allready and some people said they work fine and some say they dont and that I need a 38 for this motor.Its for a desmogged 83 fj60. I have a holly on it right now but I am tired of tuning it all the time and I had a weber before on a VW that ran great.
Before you say go back to stock dont bother. The aftermaket Holly,even with its problems runs so much better than the original ever ran.I also like the extra horsepower.Thanks

I've got a Weber on the shelf right now that I just pulled off of an 83fj60 that went back to a Mark's Off Road modified Aisan carb.

If you really want a weber, you can make me an offer.

Yes it is true that the stock FJ60 carbs seem weak in the HP department compared to the toilet bowl Holleys and Webers. But the Aisan has room for improvement, and already has superior idle, off road and mileage characteristics.

If you're never gonna wheel the rig, then do whatever you want.

Since you've already got the Holley adapter on there, I'd suggest using a Motorcraft 2bbl. It uses the same adapter. They work great and are cheap, plentiful and easy to build. It's what I run on my 2F.

Is it the 2150 your talking about?They have them new at autozone for 99 with a 30 dollar core charge.Are they easy to adjust and how is the horsepower with it?Thanks

.

How did it run with the weber and what model is it?Also how much do you want for it? I can through in my old aisan if you want it. It was running when I pulled it about 2 years ago.

I think that's the one. Mine is from an early Bronco with a 302. I'd say powerwise it feels a little stronger than the worn out Aisin that was on it. The best thing is that it works so well off road and it starts and idles great. And it was cheap.

The weber 38/38 is a better choice for a 2F than the 32/36. Neither match the cfm of the aisn appropriate for that motor. The 32/36 could be made to work I suppose...I've heard good things about the motorcraft, but have not tried one myself. I trust Jason's view as a "discriminating driver," and he deos wheel his junk, so I'd have to say it works offroad well.
65swb45 has a good rep as a carb guy, so any dealings you have with him should prove successfull for you.

65SWB45 · 03-21-2005, 11:38 AM

If you're REALLY interested in the Weber, tell me what to look for to tell the difference between the 32 and the 38 cause those things all look the same to me!

Heck ya I'd give you credit for the stocker.

ranger · 03-21-2005, 11:46 AM

32/36 will work for a 1F, but is too small for a 2F.

chef · 03-21-2005, 11:48 AM

Hey 65swb45;
38/38 both barrlelare same sized, and both open at the same time. 32/36 will have one barrel smaller than the other, and the small one opens first...

That would mean that if it had two sets of gears that meshed like a window regulator, that would be the 38mm right?

chef · 03-22-2005, 04:55 AM

Yep, I believe that to be the case...

65SWB45 · 03-23-2005, 10:01 PM

Got a pic. I guess it is the 38mm.

jnynuke · 03-24-2005, 04:56 PM

It looks pretty nice.Was the electric choke hooked up on it and if so where was it wired to.I picked up 32/36 really cheap but Ive heard it wont run that good on my truck so the 38 seems like a better option. How much do you want for it?

I know we talked, but are you still serious. Thinking about posting this elsewhere. Let me know.

Landpimp · 04-06-2005, 03:10 PM

I had never come across the specs on a Aisin before, but in some FSM I found that the early-mid 70s 2 barrel Aisan carbs were 38/38

treerootCO · 04-06-2005, 03:54 PM

The 38 38 refers to the size in mm of the throttle plates. A 32 36 has one that is 32 and the other is 36.
