Also my engine likes to run-on, (diesel backwords) it's extremely annoying as it destroys the cotton air filter on the weber. The truck did this a good amount with the stock mikuni on it too. How can i stop this from happening i have tried alot of stuff to stop if from changing fuel pressure to the fuel level in the carb bowl. And also re-jettting it and tuning it several times to try to get it to stop, it doesn't do it as much but it still does it every once in a while...
