Dellorto Float Height Confusion
Posted: Thu May 18, 2017 5:37 pm
Sorry to start up yet another topic on Dellortos!! Having read a lot of previous threads there seems to be conflicting information about float height settings. My Dellorto 40Es' have 10 gram floats and I intend to go with the Lotus advice and set them to 15mm, having experimented with 16mm. However, I noticed that on an American Dellorto website that the recommendation is 17mm for this weight of float and also a strong warning to only use Viton tipped needle valves. Are Lotus suggesting 14.5mm to 15mm because that suits the Twin Cam engine better or could it be partly due to the fact that the engine is canted over slightly on its mountings possibly affecting fuel levels? On my car I had to use the same mounts either side (level engine) to get the cam cover to clear the bonnet.
