Is he still around?

Doesn't plugging the air jet controller ports just make you run your carb richer? If so does it make it rich enough to foul your plugs?

**mindlos** · 03-20-2003, 09:48 AM

that was quite some mouth to mouth on this thread

Yeah... POS CARB (Eric) Started removing vacuum lines... And he was close to removing them all... I thinkn he was down to like 6.
The I came in and took off a few more... then me and him were discussing how to hook up the air jet. I finally ended up tossing it... but I didn't feel much difference and I was pretty sure Eric knew what he was doing... so when giving directions to other members i told them to keep the Air-Jet and just turn the rear 12mm nut out. There were other projets Pos Carb started but I dunno I pretty much took his pace whn he moved away.

unpluging air jet controller will not affect idle at all.
just remove the air jet coroller and plug the lines on the carb.
the way i understand, air jet conroller was leaning out mixture between 2000-3000 RPM.
i got improvement between 2000-3000 rpm after i took it off.
it didn't hurt my gas mileage at all.

Something interesting I notticed... the primary Air correction jet is around 160- 175 when the air jet controller is in use... and there is a difference between the 86-87 air correction jet and the 88-89 air correction jet... one has a 60 and the other uses a 65. the higer the # the leaner the fuel mixture... well the greater the braking force on the gas in the emulsion tubes. Which means if I use a + 25 + 30 ruel for the mains.

The primary main jet should be around 135 - 150

More then likely its 135 but I no longer have a way to tell and I forgot all my old measurements of the jets.

Anywho... thats why plugging the air controll jet does wonders... cause it keeps the Letter A which is the 100 air correction jet
and letter B which is the 110 air correction jet from being used.
So weighing a 65 jet against even a 135 main which is fairly small... would create such a low braking power that you'll come out with a richer mixture.

BTW letter C is the 60/65 air controll jet.

connecting B to C whould give you 170 - 175 air correction
and
connecting A to C would give you a 160 -165 air correction

This may be good later on when doing emissions testing

anyways back to my project... i thhink I'm gonna bust out another top hat from the junk yard... seems I have another plan and some of the drilling I did went a little too far. it looks real nice but I think in the lkong run starting over again will save me some greif of getting the carb to work right.

***A20A1*** · 03-20-2003, 11:21 AM

damn I reread all that... shows I can't type for beans

**mindlos** · 03-20-2003, 12:04 PM

POS Carb, aaahhhh. I remember him. Hey you are either accurate and slow or fast and get the point across. I cant type a damn so I take it at a leisurely pace. Thats why I will never be a post whore.

So, the way the carb is jetted right now, is that any close to the levels of diminishing returns with increasing richness? If I wanted to drill the primary jet I would obviously see some benefit right? I do remember a bigger size being suggested. Speaking of which, is that a risky endeavor? Is there some secondary or tertiary structural design that would be obliterated (basically making it a simple straw)?

**Mike's89AccordLX** · 03-20-2003, 12:09 PM

Hey mindlos maybe you can help me with these vac. lines. I don't know what to do with all the stuff that's connected to the vac. lines on the drivers side of the engine.

***A20A1*** · 03-20-2003, 12:42 PM

It will only be a simple straw if you remove the emulsion tube or if you drill the main jet way over the size of the air correction jet.

If you do decide to drill the main jet... then maybe reconnecting the air jet controller would keep you from fouling the plugs.

**mindlos** · 03-20-2003, 12:46 PM

Mike's89, you've got PM.

***A20A1*** · 03-20-2003, 12:53 PM

PM'S

Mike's89 your mailbox is full.

heres the message:

I put up a picture. To be honest with you I am not sure what those electrical connections are for, apart from the obvious, so I left them alone. My Haynes manual is at home so I cant verify for now. See the picture?

**Mike's89AccordLX** · 03-20-2003, 01:45 PM

Ok I removed the wires from the harnesses and removed that round thing (hope to god it's the cruise control) let me see what else I have to remove.

***A20A1*** · 03-20-2003, 02:00 PM

Yeah if you don't want cruise then remove that big round can and the Vacuum reserve bottle (black)

No need to plug vacuum lines since they are disconnected.

With A/C gone you can remove the solenoids from the right side... I'm not sure which are for A/C and Which are for Cruise controll... there are some up by the wiper motor and there are some on the inside fender wall that can be removed...

if you remove the driverside fender you will see a second (BLACK BOX) which you can also remove If you want to.

**Mike's89AccordLX** · 03-20-2003, 02:09 PM

What do I do with the tubes going to the vac advance near the distributer?

***A20A1*** · 03-20-2003, 02:13 PM

you need those... look on my how to... I connected them to manifold vacuum... i used the port at the rear of the carb... save some of the vacuum connectors that came stock with the car to adapt the smaller size hoses from the vacuum advance to the larger vacuum ports on the manifold.

**Mike's89AccordLX** · 03-20-2003, 02:15 PM

Ok let me check again.

**rideredorgohome** · 03-20-2003, 10:08 PM

whoa mindlos, where'd you get that intake dude? I wanna get my hands on one a those!

**mindlos** · 03-20-2003, 10:18 PM

Gotta go to the junkyard and get a 1989-91 civic PGM-FI box then do a little cutting and fittin. Check this thread to see the developments:

how much did you pay at the j/y?

***A20A1*** · 03-20-2003, 10:31 PM

Mindlos that pic in your sig is a nice veiw of the intake but a bit too small do you mind if I have the larger pic to post in a new thread I just made.
