The delay is huge, almost as if there's no fuel, I'm not sure how to tell if I've got vacuum secondaries or mechanical (it was sold as a turbo carby). After rebuilding it started straight up and went to 2000rpm, after playing with timing and idle screw i got it to 1400rpm which was borderline okay. Then I took it around the block for a drive, and as I got back home it started stalling again (hence why I rebuilt the carby!). Thanks for the reply, i'll keep looking into it.
Thankyou for taking the time to film and upload these videos. Do you know by chance if this carb is the same as the Toyota Corolla 4AC motor 1985-89? It's an Asian two barrel. Thanks mate!
hy, could you pls tell me where did you get that rebuild kit? i have a 1990 toyota crown with a 2.8L 5M engine and it has an AISAN carburetor and i can't find any kits for it. thnx
That Aisan carb is much nicer than the ones I have tried to rebuild, which were so loaded down with emissions junk that they looked more like a bundle of snakes than a carb...

Thanks for the videos. My greatest fear with carbs and throttle bodies are the screws and nuts which are tight due to electrolytic corosion. Any idea to loosen them without damaging the screw and carb body?
Can you tell or show us where the siphon break on the secondary venturi is? And what is an Oklahoma rebuild that can clean this siphon break without taking the carb apart? Thanks - Great vids.
It's a very wise idea to take a photo of the sides and top of the carburettor whne on the engine and before you dismantle it at all. Also at various times during disassembly of the whole thing. So helpful to enable correct re assembly.
Hi, I just rebuilt a 28/32 Aisan carburettor for a Daihatsu Charade Turbo - I followed your instructions along with the factory manual and the haynes manual yet I still have issues and I'm unsure where to look. It either idles really high or barely at all (I've replaced all the hoses) and when boost comes on there's about a 1 second delay as if the fuel cuts out. Just thought I'd put it out there - Thanks for the video though!
yes, I know the primary jet is smaller than the secondary one, any way I give it a try when I have some time and see the result in terms of fuel economy, my car has poor fuel economy, top up tank to half,fuel gauge pointer at middle mark, travel 33 miles, pointer on empty mark...
Hey Pinhead, or anyone reading this comment! I did my rebuild and it runs great. However, the unit loses the fuel as it sits and has to be manually primed to start. (a little gas into the top). Any idea what I've done wrong?
I hear this is a common issue after rebuilding this carb....I think a new float, that doesn't come in any of the rebuild kits fixes the issue assuming that it's installed correctly. Toyota still has floats available.
It is due to oxygenated or "reforumated" gas that has a lower surface tension than straight gasoline. The reason that they tend to leak gas into the primary bore after rebuilding is that the carb cleaner cleans off the gasoline lacquer or residue that prevents the gas from creeping up the nozzle by capillary action.

Use properly sized JIS screwdrivers.
Thanx for these uploads! I'm starting to feel a lil calmer now about tackling my rebuild on a '89 corolla emissions controlled nightmare carb.

Hello what if i use same size jet for primary and secondary?
One will be wrong.
yes, I know the primary jet is smaller than the secondary one, any way I give it a try when I have some time and see the result in terms of fuel economy, my car has poor fuel economy, top up tank to half,fuel gauge pointer at middle mark, travel 33 miles, pointer on empty mark...

@mike sides - I’m yrs too late, but it could also be due to the gas evaporating if your carb cooling fan doesn’t turn on and run after engine shut off
@@joyridaz Thanks buddy. Turns out I didn’t hook the choke on correctly. My teen age son found it!
@@joyridaz Carb cooling fan.......😒
What engine is this for? Will it work for a 20R?
Toyota 4a-c engine
Toyota 2f 4.2 L 6cyl
