Long time 240 owner, forum newbie wondering about a triple carb setup.

Recommended Posts

Hi

I have a 71 240 that I have owned since 1989. When I got it there was a pair of DGV's installed that never worked very well. About ten years ago when I had the cylinder head rebuilt I had a pair of Z Therapy SU's installed and they have been perfectly fine.

However....

I still lust for a set of 3 sidedrafts.LOL

Is there an argument to be made for Weber vs Mikuni or the other way around?

Size recommendations? The engine is a stock L24 block and the cam is the stage 1 performance cam from MSA.

I have triple Webers on my car and by that measure I am partial to Weber as opposed to Mikuni.  Having said that I know numerous Z owners with Mikunis who are quite happy with them.  In my opinion however, the Webers along with repair parts and jetting options are much more readily available than the Mikunis, which tilts the balance in favor of Webers.  Just my 2 cents.

Hope that helps.

Mike.

Functional differences are small between them. Most street users will never know the difference. 

As Mike W says, the real difference is availability and parts access. Webers win hands down.  Mikuni prices are going a bit crazy too. Like stroker cranks and S1 console fuse box covers, they are better investments than any stock I've seen lately

Comparing my Mikunis to my friends Webers I noticed that some adjustments were easier for me. My 40's allow for a external adjustment of the float . Very accurate too. I believe acceleration pumps are also more accessible on the Mikunis- but can't say for sure of all Weber models .
I think Mikunis are more desirable but also more $$.

Whatever you go with find someone who knows how to tune them.  Best money I spent wasn't on the carbs it was on having someone who knows what they're doing tune them on a dyno.

There you have it.. Webers for accessibility and ease of finding parts.  I highly recommend them.  They are a simple design that has many decades of experience available to you on this board to help out.  Weber junkies like to help each other. Soon you will be talking emulsion tubes and idle jets and air correctors like a pro

This is an older thread but if you want Weber 40's I'm thinking of selling mine with a Cannon intake.

The SUs are fine for my old arse and keep up with my mods plus I still have the mechanical fuel pump.

They'll be on ebay soon and I'll post the link.

Hey Fellows

It has been a while since a I dropped in here.It's good to see all the old gas heads still around. I guess when you own one of these rare beasts you never really leave.Project #6333 is still being metal worked but hoping to start it by the end of the year. Why don't I see much about OER carbs (AKA SK Racing) though. I have a set of 47mm's in the closet  I can't wait to I stall bought from Pierce Manifolds about 10 years ago. Beginning to wonder why very few have experience with them. Grannyknot made mention above. Also I can't seem to find a suitable fuel block or rail that would bring it all together. OK it's time for suggestions. Any help or install and tuning advice would be greatly appreciated. YOU GUYS HAVE SOME KICK arse CARS!

^ You know I'm not sure why OER/SK triples haven't caught on more than they have, they are easier to adjust and tune than Webers with the external float adjustment and external accelerator pump screws. Although there can be some confusion with the original emulsion tubes and jets that the early models were equipped with they will also accept any of the the Weber e-tubes and jets so that problem can be avoided. They offer a kit to reverse the direction of the 'choke' pull and a kit to fuel inject them if you want to. They are not cheap, that's draw back. I don't have my set anymore but was very pleased with them.

@Blue is now 240260280 knows as much or more than anyone about SKs

Hi esmit208,

I bought some rims for my wife's Ridgeline in Melbourne a year ago.  I usually work in Florida every year or two and would be delighted to help you tune the next time I am there.  I'll give you fair warning. :)
