Carb info

What's up guys.

I am going through a pain in the ass rebuild of my stock Hitachi carb. Luckily I have a few Mazda rebuild kits to make to happen, but this thing is fighting me. Looking to upgrade to a newer carb.

I have heard that some people run the Nikki, the question that I have is what do you need to do to convert the Nikki to run a 13b? I would guess that the jetting would need to be larger for the bigger engine.

If anybody is running a Nikki on a REPU let me know.

I am planning the same thing but I will be running a paul yaw modded nikki so should be fine.
Have to tap the factory intake for the nikki to bolt to it but I think it should be fine.

Anybody know a part number, or where to get the little brass bleeder that regulates the vacuum to the secondaries? I broke mine in half the other day.

The entire thing was filled with solder. I know some guys solder the end of it so it doesn't bleed vacuum into the car body but is the entire cavity supposed to be plugged up?

RE: Vacuum Bleed Jet

You want that bleeder blocked off. Given the age of the secondary vacuum diaphragm and its having hardened, increased vacuum is required to actuate the secondaries. This is what sealing that orifice at least intends to accomplish.

You can also modify the spring in the vac. diaphragm housing...

In any case I need to get another bleeder. Mine is now in multiple pieces. Got a part number or anywhere to find one?
