Corolla Aisan Carbs

Recommended Posts

Bolted up a pair of "single" carbs to my 3KB manifold if you know what I mean. Did this to both of the 5k's I have had in the past and felt it worked well.

In relation to the filter for the twin carbs, (I know I'm in late here) I used to use a Subaru one. I think the part number is A337 or similar.

 

Carry on.

This seems like an appropriate place to ask my carb question...

 

My little KE15 runs a stock 4k.. i bought it will a weber 45 on it which was clearly much too much carb for a stock engine, so I have taken that off and it currently has a stock single carb on it.

 

In the interests of gaining a few more herbs what is my best bet.. I can get hold of the 3kb twin carbs and manifold... can you still buy rebuild kits for them?

 

And do two standard single carbs bolt up, or is there mods required to get them to fit on the 3kb manifold?

I'm sure the rebuild kits are common to single carbs but will check it on the parts book when I get home. It's only the choke/jet sizes that differ between the two types. I have looked previously and stocked up on rebuild kits from the US ebay guys like Vintage Imports & GWS rareparts. The bottom link has the accel pump also.

 

Another aftermarket part number is AN101 which you can buy here in Aus at about 4 - 6 times the cost

Edit, that is of course assuming you use KE1x carbs x 2 and not later Corolla carbs

Doing anything to the carb system won't have much effect if you don't do the exhaust and a cam grind as well. The 4K will run a 45DCOE just fine if you do the other mods, as they will run twin 40DCOEs OK. What chokes do you have for the 45?

All K 's are common across model range, and 3K's are common across the model range.

That would be great. Ive been mucking around with these stock carbs on my 5k.

The best jetting I've got so far on the 4k unit is with 47 idle, 108/153 mains and a 90 power jet. It goes well under what but it's real lean at idle and low speed driving.

I'm think of going up to around 55 idle and 125 primary main.

I'm currently using 135 primary and 165 secondary on my 4k carb with free flow muffler 2" pipe, runs and screams like a whore
