Re: 86 civic Weber 2 barrel tuning
I'm assuming that it is not a CVCC engine (3 valves per cylinder). Am I

Re: 86 civic Weber 2 barrel tuning
The CVCC engine head has three valves per cylinder. One of them is tiny
with several small "holes" in it.
If there is a way to put a normal carb on this setup, I am (like Perot)
all ears!

If there is a way to put a normal carb on this setup, I am (like Perot)

Re: 86 civic Weber 2 barrel tuning
The CVCC engine head has three valves per cylinder. One of them is tiny
with several small "holes" in it.
If there is a way to put a normal carb on this setup, I am (like Perot)

Re: 86 civic Weber 2 barrel tuning
The adaptor plate and gasket was ported to the third small hole, I'm
assuming for the aux valve, so fuel and air can get there too. It's working
great. I was wondering what that 3rd hole was for, and now I know. I guess
It porting the main passage and the small one is enough to allow the fuel
air mixture to flow into the aux valve.
I don't know all the specifics, I just ordered the carb trusted the company.
They wanted to know what set up I had and any mods.
Turned the car over to the daughter today, In the year I have owned it, it
has never ran so good. No high idle or stalling

assuming for the aux valve, so fuel and air can get there too. It's working
great. I was wondering what that 3rd hole was for, and now I know. I guess
It porting the main passage and the small one is enough to allow the fuel
air mixture to flow into the aux valve.
I don't know all the specifics, I just ordered the carb trusted the company.
They wanted to know what set up I had and any mods.
Turned the car over to the daughter today, In the year I have owned it, it
has never ran so good. No high idle or stalling

Re: 86 civic Weber 2 barrel tuning
Steve,
Do you have the website and part numbers? Oh, and what is the size of
your engine? I'm dealing with the 1300 but I suspect that you have a
1,500.
But, I'm like you. I don't give a rat's patootie about the specifics,
just that it works...

Just tooling through cyberspace in my ancient G4
Do you have the website and part numbers? Oh, and what is the size of
your engine? I'm dealing with the 1300 but I suspect that you have a
1,500.
But, I'm like you. I don't give a rat's patootie about the specifics,
just that it works...

Re: 86 civic Weber 2 barrel tuning
This is indeed good news! If I have any problem with the current carb,
it would be a great option for me in a couple of years since the car is
still subject to emissions testing until its twenty five years old.
