.040" deck
48cc heads
7.5 compression
The dist is a VJR4br25. This motor is in a bus.
Thanks in advance!

with the 28pci it depends what venturi diameter you have as they are different. When i was using single 28pci with custom 24mm venturii had
Idle 60
Main 135
air 180

this is with the same combination as yours except more head work and comp ration of 9.1 so some where in the ball park above should help.
