DELLORTO W1600000 SPILLO W16 MALAGUTI 50 F10 JET LINE 1995-2000
Partial load or half gas can be achieved when the gas gate valve is 1/4 to 3/4 open. Jet needles and mix tube are competent to regulate the mix in this area. Needles The needle can be adjusted with a clip in 4 different positions. If the engine runs well with the throttle slide fully open, but stutters halfway, then its running too fat. You can hang the lower jet needle (move the clip further up the needle) and thus reduce the mix in this area. If the needle is already in the lowest position and the mixture is still too greasy, then use a thicker needle or a smaller mixture tube. If the yield is too low at full throttle then hang the upper needle. Needles come in a variety of thicknesses, lengths and grades. We recommend that you try different needle sizes to find which one is best for your personal tuning needs.
