Creating vacuum leak to pass emissions


Recommended Posts

Need some feedback. I've got a subaru that is calibrated for sea level. at 6500 feet, it is running on the rich side, a little too high to pass emmissions.

 

This is a carbed EA82 1.8, I think it is the hitachi (right?)

 

Anyways, I'm failing at 2500 rpm.

 

CO LIMIT- 1.5

Tested- 1.55

 

The only real way to correct this is to get the carb rejetted, which I will probably do, but I need to get this car regsitered ASAP. I can't wait to mail order some jets.

 

So, I need suggestions on a vacuum line to pull to lean things out. Preferably one that will not cause anything emissions related to stop working.

 

Best contender I see is one right behind the carb in the middle of the manifold. What goes to this?

if your gonna do this, you can go to a pet shop, and get a valve for an air pump for aquariums, then you can tune in your leak... :lol:

 

just get a T and leave it all hooked up. hide the bleeder. or just get it hot, that helps alot

This will be temporary. This vacuum leak will exist for 2 blocks. One block driving in, and one block driving out.
