I am finding that my cold idle and hot idle are very varied. If I set my cold idle to be reasonable so it doesn't shake it's tits off if I don't put my foot on the throttle then when the fuel pump has warmed up it is idling about 1300 rpm which is really annoying. I am still running the cold start spring but have cut the cold start cable off the wax thermostat because it was too long (I had a Lucas pump originally). I have tried using both the vertical idle screw and the horizontal one, neither can seem to get a consistent idle. I am still running the cold start spring inside the pump as well. I have changed the fuel filter which helps to get the cold idle closer to the hot idle but there is still a difference of a couple hundred rpm.
