Can someone explain how much fuel should flow down the line to the carb? I am having an issue when the car gets up to speed about 80 km/h. Once at speed it's like the engine starves out and stalls. Once sitting for about a minute we start back up just fine. I took the fuel line off last night and ran some fuel into a jar the fuel looks really clean but it seems like a small steady trickle into the jar... I thought it looked slow but I have no basis for comparison.
