Triple SK Racing Carb Setup

[rosaaen89]

good afternoon everyone, 

 

I am curious to know if anyone might know who would rebuild these or where I could find a rebuild kit for a Triple SK Racing Carb Setup? they've been sitting for years and i would assume they'd need a rebuild or cleaned up at a minimum.

I've never used this service, but i see lots of people on Instagram use http://kyushahouse.com/

Kyushahouse would be about as good as it gets for SK carbs.  They are on the rarer side here in the states.  OER still makes and sells parts for them, but it's hard to get them here these days.

yeah i emailed them to see how much it’ll run. i think i spoke to another guy about that shop and he said it’s like $1200 to have them rebuilt but i could be wrong. we will see since i just emailed them last night

Replacing gaskets and cleaning doesn't take long, so it shouldn't be too expensive.  I would say 2-3 hours worth of work. 

 

Completely taking them apart, vapor blasting or similar, all new zinc hardware, fully setup takes a lot of time and will cost $.

hopefully they contact me back here soon. i tried to call another shop locally but haven’t responded to me either, also idk if they’re really familiar with datsun related carburetors but it was a carburetor specialty shop.

The two barrel side draft carbs were used on many different cars, not just Datsuns. Find a supplier that can get rebuild kits and do it yourself. It is easy.

Or, find a shop that specializes in carburetors and be prepared to spend a considerable amount more to pay someone else to do the job.

The installation and tuning is where the skill comes in. Having a set of various sized jets, a tool to read the spark plugs helps. Even better is having an exhaust gas analyzer to get the carbs set and jetted correctly.

Get it too rich and it will consume excessive amounts of fuel, and wash the cylinders down, shortening the life of the cylinders and piston rigs, pollute the oil and risk bearing damage.

Get it too lean, and melt pistons.

Oh, and when the atmospheric pressure changes, you’ll need to check and change jetting.

this might be a dumb question , but if i get these rebuilt and put on is there any additional parts like linkages or anything else needed or that would need modified to work or are triple setups bolt on?

[duffymahoney]

Going triples isn't for the faint of heart.  If you love to tinker, or have access to a local carb tuner, then I say go for it.  If that isn't your cup of tea, stay away.  They are not just bolt on and go.

Difficult to tell from a couple snapshots on a phone camera.

Did they come with airhorns?

Did they come with an air box and filter?

Intake/exhaust manifold gasket?

It looks like they have a J hook set up, some some linkage is there for the throttle. I can't tell if it is all there though. 

They also appear to have K&N backing plates, If you have the rest of the K&N set up that would suffice as an air filter set up.

i don’t have the filter setup or airhorns for it but i wouldn’t mind getting either for it . it don’t have any of the gaskets either so i would have to get those as well. i was mainly just wondering if there’s any additional linkage id need to buy or have modified
