Toyota Corolla Carb

I just finished putting om a rebuilt 78 Toyota Corolla carb with a manual choke for my factory model - 168k miles carb. Runs great in driveway haven't put on road yet. Stupid me, forgot about the coolent connection and when first cranked up anti-freeze everywhere!

Question????? NCO's technical article doesn't mention what to do with the two coolant hoses. I have plugged both for now. Should they remain plugged? If not what do do with them on the Toyo carb?

HELP!

I'll post some pictures later, if it runs ok on the road.

Re: Toyota Corolla Carb

I seem to remember using 1 of the water hoses to connect back to the other outlet and make a loop. Nothing really looks out of place back there and it's never been a problem so that must be it.

Re: Toyota Corolla Carb

I suspect that the Toyota carb has a choke that is driven by the coolant temperature. My weber is the same.

I checked mine just now and the "water choke" is hooked up like this:

One hose goes from a connector on the firewall side of the intake manifold. There is a larger water line right next to it.

The other hose goes under the intake manifold to a small connector on the coolant manifold -- that long pipe that extends out of the rear of the water pump.

I hope this helps!

Re: Toyota Corolla Carb

Don't think your suggestion will apply.... It is a manual choke, don't see how the water temp would effect it???? But, maybe so... NCO chime in here need to know


Thanks

Re: Toyota Corolla Carb

Like Toyguy said... run the coolant hose looped from one outlet to the other, bypassing the carburetor since it is not needed.

Re: Toyota Corolla Carb

DOH!

Me have stoopid attack...

Run a hose from one connector to the other, if you haven't already.

Let us know how it runs and what year and model you found it in!

Ack

Re: Toyota Corolla Carb

Took Zuk on road today. Runs like a top, got my idle down to 800 rpm. Went up only hill here (bridge over intercoastal waterway) normally Zuk slows down and have to downshift to 4th to maintain 55 mph, made it at 55 mph in 5th. I got the Carb from Advance auto (rebuilt). I asked for a 78 Corolla 1.2 liter carb. The only problem i'm having is the cheap Advance Auto choke control, it doesn't have enough tension to hold the chokes position (i'm using 1, 2 or 3 closthes pins to hold the choke knob where I need it to be. I'll have to work on this... The carb doesn't exactly match the photos in NCO and others who have posted pics of the Toyo carb switch, howver it works just fine. It really went well for a old 64 year old fart with no great mechanical experience. Thanks for all the pictures posted on the BBS. I'll post mine before the end of the week.
The greatest thing of all was yanking all the vacumn hoses off....

Re: Toyota Corolla Carb

I used almost the same mounting that Toyguy posted when he switched to a Toyo carb. Howver I did not reverse my carb as he did. I used a similar aluminium angle pieces to build a support for the accellerator cable. the choke cable fit right onto the carb with no changes necessary. My Dremel cut off wheels made the job of cutting a slot in the aluminum bar stock angle go real easy. Don't no how I ever got by without my Dremel tool.

How much choke do you need in S.C. ?? [img]images/graemlins/grin.gif[/img]

I have the same problem with holding a choke setting, got a piece of clear tubing with some steps cut in it that fits between the knob and dash and does the same thing.

Glad it all went together for you, this is a fairly easy mod that makes a good difference in performance. If you make a free flowing filter setup you'll gain a bit more.
