My Bertone 2000 with Dellorto DHLA40 is now almost there in jetting.
I have put all new jets acc to the recommended, and it runs well.
BUT at very low load, like 50-60km/h on 4th gear (round 2000rpm), it wants to jump a bit, as soon as an uphill comes or I go a bit up in load its just fine.
Tried the mixture screws, but it does not help. They are about 5 rpm out btw.
Sync is ok.
Any ideas where to start?

Hi again, did get the 55 idle jets yesterday, and it feels better!
Not fine tuned so far, but is promising.
