Hey guys, I gave my dellortos a basic tune last night, just by what i have been told and i was wondering if anyone has any hints or tips for tuning them. Roughly how many turns out should the screws be? I know it depends on the motor, which has run [email protected] without the dellortos being tuned. I have set them all at 2 turns out for now, and it doesn't blow any black smoke when it revs or fuel up at idle. Although i did fuel up a little before i wired up my multiple spark ignition.

I Pulled all the linkages off cleaned them up, set all the idle screws on the carbs then put the linkages back on and adjusted them so that the throttle on each carby was touching the idle screws. Then I used a bit of pipe in the carby and listened to the sucking noise of first and second carby and adjusted the linkage untill the first and second carby sounded the same and locked them both off. Then I listned to the second and third carby and adjusted the linkage on the third carby until it sounded the same as the second.

Can anyone give me any hints or tips for tuning them?

cheers

Les

Ask Greg 82911 as I believe he knows his way around Dellortos.

One thing I do(well did actually its been a while now ) is
using a tacho adjust your idle mixture screws to acheive the maximun revs

wind the screws in and then wind em out slowly and whatch the revs
they should rise ,peak and then drop off

(this was for webers but should be the same)

another thing is to short out each plug one at a time and see if you are getting an even drop of the revs (give it a rev in between
each one)
