None of the carburetor equipped Civics/CRXs have computers. The solenoids in the emissions box are vacuum-operated - when the vacuum reaches a set level, the solenoid is triggered to do whatever it's set to do. If there were a computer, there would be a port to plug a reader or computer into. Modern vehicles do the same thing, except they use an electronic sensor at the vacuum source (or intake or exhaust - whatever is being measured), and send the information to the computer via wire. Fewer vacuum hoses means fewer hard-to-trace (and diagnose) leaks.

actually, that's not right,The HF has a computer,and the vac boxes have electronic vac controllers and vac pumps

Sorry to revive an old thread.

Not a bad thread to revive.

Mines up for sale.

when i ran my weber on my 87 CRX DX, had D15A2 w/ 213k miles, i noticed that when i hit the gas that the carb would shoot out some white vapors, im guessing gas??, would the Cat not being gutted have something to do with this?? if not then why did my carb do this??

when i was having trouble getting everything running correct, i would get those puffs of white when it would die , idk

woudnt die, ran just fine before i took it out, but it only put out that white vapors when going over 4-5k RPMs

How many dollars,My good sir?

Sold it for 200 including the ported manifold/devaced and throttle return spring and bracket.

thats a great deal !!

Nice job !

hey i just installed the weber on my 84 1.5, got the air/fuel mixture screw and the trottle screw dialed in what i beleive is correct, but now when i turn it off it diesels down and "knocks" and i have no clue at all why it is doing this i need some advice, i dont know much bout cars. i did the devac tried my best off of pics i could find on this site maybe if someone has does this same set up if they could shoot me some pics or something.

Just finished devacing my car, I broke a bolt on the manifold so I'm getting that out next, kinda holding it off till I get other simpler things finished first. I have a few questions... 

 

Where does the valve cover hose go now that it no longer has a place to go? Do i just leave it be or plug it up? Also theres a hose going from the manifold and does a 180 straight down and plugs into somewhere on the block i believe... Do i keep this?

Alex, just put an autozone filter on the valve cover hose and the hose that does a 180 goes to your PCV valve, leave it hooked up.

Eddy, you probably dont habe the mixture set right. Try richening the mixture a bit and see if it gets better/worse and adjust accordingly. I had the same problem with mine when I did it and after readjusting the mixture the problem stopped

I have a 87 civic wagon and swapping the engine from a 86 crx dx engine code ew1.if i do a weber conversion which one do I need and do I do away with most of the vacuum lines

BUT. No one talks about the aux port to the intake valve..

 

If they're all coked up and poopy, it won't matter how much you spend on a carb/carbs, it's gonna run like crap

since the tracts are basically plugged.

 

messed with these for decades with the cvcc stuff.

The best I cam up with is to use some 3/16" cable (fray the end for about 1/2"), put in a cordless drill and have it rotate the same way as the 'twist' and force it in to clean the coke/carbon out.

Keep doing this til it flushes clean.
