** There can be different from the setting value of the actual are the manufacturer standard value. It's become a symptom, for example, such as stalled as "Gobogobo~tsu" when intense lateral G took it cry almost necessarily bite the air, "the waterfall climb carp" intense length, with lateral G in the hall led to the center venturi

To go sucked (the only gasoline) product gas that is a state, it is considered a symptom caused to become "dark" state time.

It is not so that does not reach the hole down the oil surface As a workaround, but the numerical values ​​we try to avoid here value because it also involved in (condition over the next G) ride of the people.

To say that the lower the oil level, please also consider the connection to the main is also a little slower.

There is a difference of reaction to G in any vertical cab or horizontally. ← here Add

My Interpretation:

Intense lateral G force and cause fuel to rises up inside the carb and flow into the passage leading to the center venture.

This fuel-only entering the main circuit's aux venturi causes a rich period.

To prevent this, our work-around is to recommend lowering the fuel level based on the G loading of the individual’s driving and G forces in the carb.

Please also note that lower fuel levels will also delay the main circuit starting.

The reaction to lateral G force is different between vertical(side-draft) and horizontal (down-draught) carbs

I'm happy to see more people are using Sk/oer Carbs.

I have a set of sk 45 units with matching sk manifold and my roomate has oer 45 units with a mikuni manifold. We love these carbs. I will be doing a blow through setup with mine using an Hks surge tank. I have been searching for an sk unit but have come up short.

Good info and good luck with those. Remember to post (a lot of) pictures of your setup. I just noted, my first post was about selling these and now i have installed them in my Z, what the hell happened?

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.

mildsquare, great info, I've had a hard time finding history on this company and it's nice to see this stuff ending up in one place.

Blue, did you take those pics while you were in Japan?

just hoovered from the net....I may put more up in this thread

[mildsquare]

By chance would any one know if a webber dcoe throttle shaft would fit an sk? One of my carbs, shafts is bent and the throttle plate started digging into the carb itself. Not too bad, but enough for me to take it off and go with another unit.

I'll have a look today.

[240260280z]

You will have to check with someone who has dcoe45's. dcoe 40's are no go.

I just checked dcoe 40's with my sk40's and the sk's have a thicker shaft with the 4 plate screw holes having different spacing. The end fasteners seem 1mm bigger on sk's.

mildsquare, ask Brian at Z Car Customs- JDM - HOME: how much it would cost from Japan, I think you might be surprised how cheap it can be, the price for parts are reasonable. Your looking for part #64
