I've got Dellorto 36's. Anybody know what the relationship is between the bypass screw and the mixture screw? How about base settings? To begin sync?

Like Webers, Dellorto has a Tech Book that you can get at Amazon or CB Performance. If I can find mine, I will see if the offer and baseline specs.
The mixture is just that, it controls the air/fuel ratio, one per barrel / cylinder. The bypass screw IIRC is to fine tune the sync (i.e air flow) between the two barrels on the carb. I am pretty sure that the Tech Book doesn't really encourage you to mess with that. The idea is that the idle screw on the carb controls the idle for both barrels. But in some cases, the individual barrels will not have the same air flow. I assume you have a Synchrometer (if not, get one). If that is the case (and it was with ONE of my Dell 40s) you use the air bypass screw to equalize the two barrels. That way when you adjust your idle screw, both barrels will be in sycn with each other. I strongly recommend you get the Dellorto Tech Book. good luck. |
