Difficult to swap an H22 into this?

[Pokémon]

I have an 1991 model Accord with F20A3 carburated engine. Recently the engine has been idling between 1600-1800 rpm when cold and 1000-1300 when warm. Since I've got about zero usable knowledge about electronically controlled carburators I've been thinking about swapping in a H22 engine but I'm afraid that it might not be a realistic idea.

What do you guys think?

You would need to convert to fuel injection, obviously. That could be fairly complicated. Not impossible, though. Since all CBs in the US and Canada are fuel injected, the majority of this site's population probably doesn't know much to help.
evil_demon_01 might be able to offer some assistance.

where do you get one of those? a carb'd CB? i hve never seen that before

[deevergote]

That's because you live in the US.
Pretty much every other market had them.

If you are electronically handicapped with carb'ed car, what makes you think it will be better to have H22 swapped in?

It would be more electronically challenging to pull off, won't it?

I would ditch this idea. It's really only something you should attempt if you just want to say you did. If you can find another CB in your area you'd be better off just purchasing that. There's too much work and cost involved to swap it over to fuel injection.

If you're looking for a challenge you could look into fitting a set of 45mm Weber side draft carbs to an H22. Ignition timing would be the other thing to consider...... However, if you are looking for a quick swap.... PGM-FI H22 into carb Accord would not be my choice.

Thanks for the input. I've scratching my head over this idea for a while and pretty much realised already that it would be pretty hard or near impossible for a novice like myself. I've come a cross a 2.0 fuel injected CB in my area which is for sale, might be able to mix an H22 into my car with parts from both cars.

The only reason why I'm considering this is because this car is really solid, very little rust which is amazing considering were it has been all its life. Don't want it to die just because the carb is screwed and all the parts I need to fix it are not available from Honda anymore.

It's not that I'm electronically handicapped in fixing this car. I've been neck deep into PGM-FI all my life and pretty confident in how to fix those engines. This is my first PGM-Carb Honda and all those vacuum tubes and sensors are whats getting to me, i.e. tubes which should've vacuum but don't.

I didn't mean to insult you in any way when I said what I said.
I took in information you posted and commented on it.
If you have wealth of knowledge on working on our cars equipped with FI, you'll be tremendous benefit to us all.

Welcome to the forum.

If you can find a fuel injected car to take parts from, it should be fairly simple. You just need to be sure to swap over ALL parts that differ between the models (I believe the fuel pump may be different... not sure on the lines.)

I say keep the unique f20.. Anyway.

Does it smoke and kind of putputput when its running? If so its probably a choke pull off problem. You could check for vacuum leaks along the carb.. Um.. Also, if your throttle cable is too tight that'll make it idle high. That's all I got, sorry if it doesn't help. Try looking up stuff on those late 80's model Hondas. I believe 89 accords were carbs, could be wrong.

What is that sprouting out of the header's heat shield? Obviously it's for the carburetor, but what does it do?

Carbureted VTEC would be awesome...

[Granite CB7]

^pretty sure it's EGR or I wonder if it warms up the carb?

[Jarrett]

Can you not rebuild or replace the carbuetors?
