I played about with the carburetor on my Flatfender Ford V8 trying to get it to work properly on steep inclines where it kept spluttering to a stop at crucial moments, but eventually decided that fuel injection was the way to go. So in 2000 I invested in a Holley throttle body fuel injection system from the USA. That was a big success but needed constant fiddling and adjustment to keep it in tune. I eventually swapped the ECU for a Microtech unit in 2005 and found it much better. Now I can control every setting from a laptop and once set it automatically adjusts to suit conditions. With an additional upgrade for timing control now it is even better.
At least I don't have to worry about the engine spluttering to a stop on steep rocks anymore.
