How to Balance & Tune Idle Triple Weber Carburettors

In this video, we show you how to do a basic tune on carburettor balancing, idle mixtures and idle speed on a Triple Weber Carb setup. This set is on a 202 in an EJ/EK engine bay.
This set uses our house engineered ProHex Linkage setup.

Best advice is to start by following the Weber Tuning Manual and use the progression holes to align the throttle plate on all 3 carbs to be in the same position - which is the edge of the plate obstructing the first progression hole. If done correctly then the air flow meter will show the same on all intakes (assuming the throttle plate shaft is not twisted).

My idle mixture screws do not respond to change the value on the synchrometer like that, no visible chanege in fact.

Hi. Please check to identify the right adjusting screws: Idle speed screw, bypass screw (not demonstrated in this clip), and intercarb balance screw (on floating carb linkages) will adjust air flow on the syncrometer. Idle mixture screws will alter fuel mixture strength (not measured with the syncrometer)

hey what linkages are you guys running to the carbs?

[@donwest5387]

"tune idle"?

Hi can you help, my weber dcoe 40 (italian) leaks fuel after a hot run from the O Ring, between manifold and carb..... im running the smallest facet fuel pump so not sure it is the fuel pressure..... and its only after the engine shuts down... look forward to your thoughts

[@andrewb3497]

Very important to check for fuel leaks as shown @2:37 !

Thanks for this video. Can you do a video on what the differences are on Weber carburetors. Choosing the right one for your car etc.. E. G Weber 32/36 ,34/34, 38.. Would be awesome for beginners wanting to understand Weber's.

[@andrewb3497]

Have a look at the Weber tuning manual (also some details shown on this video : ua-cam.com/video/qndixQxhV_8/v-deo.html )

superb can you just confirm when you are balancing and you disconnect the linkage i am assuming the adjustment you are making is the effective the tickover screw as i cant quite see? On my triple set up i have all three carbs connected to the throttle bar so i guess the best way will be to disconnect these and try and balance them to the carb that has the throttle cable connection I am assuming? Great video best i have seen

[@andrewb3497]

Best practice is to have them all disconnected and start by adjusting each carby throttle valve so the edge of the valve aligns with the first progression hole. With this done each carby should flow the same and as such they will be balanced.

Hi !
My name is Israel
I have a 1980 Toyota corolla with 3tc engine , with 45 DCOE Webers carburators. That need to be tuning. Would you please give me some advice ?
Also where I can get the linkage system you have in the video .

Thank you very much!

still very rough and eratic for 1000 revs .....all very hit and miss.

Did you miss the bit where he said it had a lumpy cam?
