Dual carb set ups - ?

[Os7213]

Hi guys.
When you using carbs you dont need the ECU since the fuel\air delivery is completly assume by the carbs. Your engine can work with only carbs and trigger wheel, the wheel serve for ignition timing.
Since you choose to go high rpm you will need something better like an MSD digital6 to ensure ignition at 7500rpm+. I suppose your setup work with Edis4 setup or something like this? Do you know if the ignition besome really unstable at 7500rpm+??
For the carbs the only think you can change is jettings, the jets are in the carbs and allow the fuel to be sprayed in the ports! So if you get bigger jets you allow more fuel in the engine. You can also redrill the one already installed, its a hard job to redrill but its can save you few dollars if you dont really know wich size to use for your application.
Note than the carbs need to be ajusted each time the atmospheric pression change...like in mountain,rain ect... And that where is a pain!
Carbs have also good throttle response. So for your problem with the engine light...you dont need ECU anymore,no sensors at all, ithink you can even unplug all the ECU and sensors and the car will still work perfectly! The only way you can control carbs is by jets and hand ajustements.

Hope i have help
