Poll - Carbies

[coupe72001]

Having had a bit of a nightmare with all my carbies (twin SU, twin 260Z Hitachi and C210 single carb) over the last little while I was curious...

What carbies are you old-schoolers running on your cars?

How many?

Where do you get them serviced, or do you DIY?

Do you love them, or do they cause you endless pain and suffering?

Ringing around Melbourne its hard to find anyone that will even TUNE my carbies, let alone for anything less than a small fortune.

got a set of Keihin flatslide carbs on my Honda Fireblade

(for sale)

love em. the sound of flatslide carbs opening up at xxxkmph is heaven.

tinkered a little with the tuning myself, but left the overall setup to an ex-500gp racer who resides in Adelaide; he's a wizz and charges $30ph.

however, when the tune gets on in time you can definately tell that the carbs are going "off" as such. good luck with finding a reputable tuner tho.

Had twin webbers and they were a bitch to tune..... Wonderful when it was right though

The key was getting aero spec lines, rods, joins etc as they don't flex or move much (if at all).

Also had a 350 holley with 500 jets and it was fairly easy to tune

Did it all myself, but got my hands on some workshop manuals to help me the first fwe times... Trying to figure them out without em would've been a nightmare.....

Some of the older jap carbies are really easy to work with as they have less parts...

The 260Z carbies are WOFTAM.

Have you talked to Lindsay at Z Shop in Glen Iris?

Im not actually sure what WOFTAM is... but im guessing its not World Of Fun Times And Merriment.

Actually, I have dealt with the Z shop guys before. They will actually service my car, which is a plus... But I'm open to making new friends in the industry. Their time is certainly worth more than $30 an hour.

BTW Tangles, I had a set of quad Keihins on my old Honda 1300 Coupe 9... Sigh... they were very special.

i was using 240z 3 bolt hitachi's ( dome tops...) werent too bad, but once they are worn out ther are a bitch to get parts for.

[MrAnderson]

are your carbs a matched pair? adding carbs from one car to another or mixing and matching can be a real nightmare to get running right... it might be worth your money getting em synched properly and then getting it tuned. the only time i have ever heard someone complain about carbs is when they were not factory fitted ... once their set right they will stay in tune for a long time (at least webers do) theyre should be a few places in melbourne that specialise in carbs.

If off the line sluggishness is not a problem, try looking at a set of Triumph 2500TC 1 3/4 SU's, if a manifold is available.

I think MGB's also ran them but I think they were 1 1/2's.

They have an infinite amount of jet & needle combinations available for them and are still relatively easy to get.

I found them far superior to the Jap copies it wasn't funny when I was running them on a 180B SSS.

The air speed through the carbies is not good from a standing start, but once moving it was a very good combination.

The same thing was found when using Dellorto's Vs Webber's in my early days when playing with Hillman's, the smallest Dellorto was 42mm but 40mm Webbers were the best.

Tuning is relatively simple, if you buy a balance flow guage.

And WOFTAM is W aste o f F @#king T ime and M oney

My only experience with new SU's was a pair of HIF6's with the non emission manifold on a stretched L20B - 2340 . The later HIF 6 series SU's have the central lower fuel bowl compared to the early "out on a limb" types ie HS4's and HS6's . It helps with fuel surge as the bowl is concentric with the needle and jet .

SU's will always have problems with radiated heat particularly with engines that have exhaust and inlet manifolds on the same side ie real Minis and the L series . Later HIF series had a kind of metalic strip compensating device but it was of limited value .

A bit of care needs to be taken with these vacum venturi carbs to avoid iceing in humid climates .

Cheers A .

Thanks for all the replies.

After a bit of shopping around I decided to get my SU's sorted by a pro. They are going great guns now. Anyone looking for a Datsun/carbie friendly mechanic in Melbourne should look up GMA Motors in Yarraville in Melbourne, as he actually used to rally a C210.

Just for the record; my SU's are 1 and 3/4, with water cooling for the manifold and a heat sheild for the extractors... and yes, they are certainly working out better than the 260Z carbs... WOFTAM, heh heh, should have worked that one out.

Anyone out their doing something different with carbies? Anyone had a go at running triples?

There is a few 280z racecars around my area in new zealand one has a fully worked L28 its like nearly 3L and has had thousands & thousands spent on it and it has triple 45mm (or was it 48mm?) dellortos an god dam it sounds nice!, like easly the best sounding N/A car I have ever heard and it goes really well in its class like gets up there with the top runners quite often! Tryed to find some info on the net but cant seem to find anything on it though sorry!
