SK racing carbs

[Reverend]

Koalia, VERY pretty! Did you take pics while you disassembled and cleaned? Are you going to add air filter screens or "suck dirty" ? I saw 2 Z cars at shows this summer that had no air filtering of any kind and it wasn't just for the show, they drove that way all the time. Couldn't do it myself.

I did open them up but they were quite clean, so i did not do anything to them. I have set of new gaskets ready to go if the old ones (which look quite new) starts to leak. Im looking for decent priced air filters as we speak, i wonder if these are any good or should i go with the "traditional" style filters: 2 x RAMAIR Carb Sock Air Filters Double Trumpet Weber DCOE Dellorto DHLA CS-901 | eBay

Those foam filters look great and a lot easier to get on and off then the K&N filters.

Thanks blue! Thanks Grannyknot! I bout my surge tank fron Brian. I'll have to contact him. I found a set of 45's i'm just waiting for them. Once the car is up and running i'll try and fix the down carb.

Here is a pic of the tank setup. I bought the carbs with a twm manifold but as you can see it's too long and brings the surge tank inlet too close to the shock tower. The sk manifold remedied this but stil isn't as short as a mikuni manifold.

According to the manual, there is "another cam" for cold start circuit, dang.

Hey all, my oer's came in. Older set from JP. Just wanted to let every one know some tidbits I discovered that Might not have been covered, if they have sorry for the double posting.

Well i made 2 carbs into 1 by utilizing my top half and a working bottom half. What I found out was Oer has 2 types of

Jet tower setups. A stnd mikuni jetting style and a weber type. The sk set on my car are weber style but the newer oer set are the newere stnd type. They do not interchange and you need to use one or the other.

Its an easy fix by swapping jet towers,but if you want to order a new set or find a used set ask the seller or specify what type of jettings it uses. So you can plan accordingly.

Type stnd or

Type w.

Well that's interesting, it would be good know when that change took place.

Any chance you could post some pics of your jet towers and the rest of us could do the same? But then SK may have just changed the Dia. of the hole and thread size and not changed the outer appearance, worth I try.

Yup, will take pics tomorrow. The towers are the same on the outside. The emulsion tube holes are def different dia. The weber tubes will thread in but not rest like the sk tube and cause the main jet to get stuck. Not that I'd know what a pita that's like .

Sorry for the late reply.

So here are mine, the air jet looks like your second photo so I guess that is a Mikuni style of jet, but my idle jet holder is just slotted like on the blown up parts diagram and not like yours. I'm pretty sure my carbs were purchased in 1999 new from OER.

Just like z's, same body different little bits. Good thing more of us are using these and info is flowing in.

It's so friggin cold out in the garage even with the heater on full that I'm trying to do small jobs that don't take too long.

SK/OER carbs have this 1/2" dia hole on the face of the intake, a breather of some kind. We have a lot of pollen bees around our property and they are forever looking for any hole they can plug up with mud, eggs, larva and more mud so this is what I came up with to try and defeat them,

So far they feel pretty secure.

Man, it must be January if I think this is worth posting.
