- 20/20 Spaco 20d carb, and pulled the two , I think youíd refer to them as jets. The big one up top says 160 , the main body has a E3 and on the deep end of the main body the main jet says 118. The second jet which I think is the pilot jet says 50-120.
I searched a bit to find a break down of these carb for proper lingual but wasnít very successful , so my apologies.
- I also included a pic of the filter on the carb
- I have the BGM exhaust
-DR 180 top end and I think the only upgrade on motor is the Rich Nice crank which Iím pretty sure, anything but the top end is the pertinent information looked at.
-Ducati ignition and Pinasco Regulator.
-Looking back on old messages from the builder, the motor is timed at 20-21 btdc, retarded it a bit more than stock to keep motor running cooler.
I'm not sure why the carb was setup up the way it is other than the 118 is recommended for breakin and that the motor was benchtested to his soecifications which I trust, but I would like to get an understanding without having to be an annoyance to the builder as I know he is extremely busy.
So to start with could you's please explain what these jets represent , including the air corrector etc , kind of in laymans terms would help alot. I do know from experience the piolt jet is for low speed and main jet is for higher throttle opening ie hiway speeds.
P.S. I don't think I have enough time in my lifetime to both read and understand CM's highly technical Sidecar thread .
Thanks for the input
