A fresh batch of Kent Formula Ford engine (Weber DGAV) large head idle speed screws finished off today and now headed to San Jose CA. We made one of these large diameter head screw assemblies for a Formula Ford engine build we recently completed and observers of that build progression requested we manufacture some more screws.
The large diameter head allows quick and easy temporary idle speed adjustments to be made by hand for elevating idle speed temporarily (and then returning to the previous setting), during pre-race warm up in the pits, without having to go diving for a screwdriver or someone having to stand (idle…) holding the throttle partially open by hand.
