How an Aisan Carburetor Works

For those of you who want the copy of the carb cutaway I use in the video. Here is the scan of it.

I said last year I had a carb issue. Well after some investigating it has been determined time is the reason and not my modding. Since this carb looks more complicated then a typical American carb. I go over it then explain what caused the failure.

I just love these carburators, I've been spending almost a year meticulously tuning mine, used to be california emissions, but i converted it to federal, new ecu, added emissions components. They just drive so nice if you can get it perfectly tuned on top of also having all emmision components working together, I'm so close to perfecting it that it gets 40 mpg going 80 on the freeway, its not slow for a typical 4ac aisan stock setup. My head is a 4A-E mounted to a 4a-lc block. Keep up the good work man, your build is ingenious.

I said it in there. You pull the vacuum secondary apart and replace the spring with a lighter one. Or you can cut the spring. When you are doing that, a lot less vacuum is needed to open the secondary. So it opens sooner.

[@THEMOWERMEDIC1]

Wow this brings back memories. I was 14 when I ripped the carb off my dads 77 Toyota corola and rebuilt it. It looked very similar to yours. Thanks for posting and great tutorial!

[@waltermahlangu479]

Thanks for the video you just saved me gonna change the float coz there was too much gas when I was rebuilding my carb

[@vettafaene]

Thanks! It may come in handy. I'm about to buy a AE82 (maybe this weekend.or Monday) and I will check the carb right away (not that I will find this type of carb in it) . It's a pretty good bargain : 3.500 Norwegian Crowns (Kroner) for the car is about 589,45 USD. No rust in the canals, paintjob is good, some minor rust inside the front wheel arches, the interior is in really good shape and extra set of wheels....And yes, i'm looking forward to buy the car =)

@1thecarnerd Sorry for the wait. Could be choke. The engine stalling sounds like float issue. Check the level in the bowl. Then get back to me.

[@Nivicoman]

I tried to rebuild a Mikuni carb for a Dodge Colt. The rebuild kit did not have the choke pulloff diaphram (which was torn). The whole thing was riveted together so I had to drill those out then find self tapping screws to put it back together. It never was right after that. I hope the owner get a new one. Apparently the Mikuni is a throw away carb.

[@84hachi]

@BOOOSHtube 1. It opens the secondary butterfly. Giving you more power. 2. When vacuum pulls the spring inside housing, it opens the butterfly. 3. The easiest thing to do when its broken. Replace the diaphragm inside.

[@Cptntasty]

Great video. I have 3 engines running this carb (earlier model) and they all run rich, now I know where to look. Cheers mate :)

[@84hachi]

@1thecarnerd Since it is a computer controlled carb. I would get those thing hooked back up. And for extra safety Replace the o2 sensor.

[@84hachi]

@powers057 Replace your PCV valve. It's clogged if it runs like crap when its connected.

[@AngryNorwegianFisherman]

good video, im battling an aisin on my sj413 of samurai over there.. and it seems that im going weber with manual choke.. idont know but this is my first carb car and this carburator just seems incredible complex. it runs rich and autochoke goes mad..

[@tec50167]

Good info! There r some videos on youtube that suck for giving info. Thanks.

[@peculiardreamz]

this is exactly whats wrong with my carb :) thanks, i might be able to fix it now!

[@yndarjabelo]

@84hachi Thank you very much, I hope I'll be able to fix it.

[@nexusmac96]

i have these carbs on my 2tb from my ta23 celica i believe... very helpful video, thanks :)

[@banpeinet]

Good info! I'm also rebuilding my double 2T-B carb for my Carina and it certainly did explain some things. :) Hmmm... What will replace it then? A set of mikunis? :P

[@84hachi]

@TICOOCIT2 I posted the pic link in the description.

[@christopherirons4025]

Where can I get a carb like that or one that is identical enough to work on a 93 Suzuki swift.. G13b engine

[@darklonleyheart]

need help on my 1984 corolla, how do i know if vaccum to distributer is well placed, and doing it's job, i feel my car a little vague on 4, and 5fth gear

[@davidloren726]

hi, I have the same type of carburetor with my ae92 4af carb engine ... I'd like to know what will be the cause if the secondary throttle doesn't open at all? because I think mine is not opening... could it be that there is problem inside of that vaccum pump which triggers the secondary?

[@paullalance4468]

i have the same problem !!! my second throttle doesn't open at all ! i have a 1989 mazda 323f bg with pop up lights

[@paullalance4468]

An old man had the same 323f bg as me and sold me a lot of things for 100 euros I have a complete aisan 28/32 the same as me but mine has 240 000 kilometers This one has 60 000 😂 i changed my gearbox too by the way Tank you for the explaination !

[@84hachi]

@Nivicoman And how you can get a set of 4 on ebay for 75 bucks.

[@applepoop10]

I have a 1985 Toyota Corolla (E80) with the 4A-C engine. Does it use the same carb?

[@84hachi]

+Ian Above Yes, it is

[@84hachi]

I've been fine. As for the car. You will just have to watch :D.

[@84hachi]

@BOOOSHtube I copied that out of my Service Manual.

[@84hachi]

@JaRabbit69 My Corolla.

[@24rocks48]

ok ok lol. Im guessing you put a weber 32/36 on it.

[@KenCarTechMeow]

can't wait for the start up vid. ;)

[@84hachi]

Seems the float is gone. Rebuild the car and you should be good.

[@cncfan]

looks complicated
