blanked off the PJ
main 280
pilot 27.5
slide 4
needle 5el68
middle clip
On a reed valved MBRT 225 with B-Race stealth expansion
biggest facto i found was getting the right pilot. 40 drowned it, 20 no adjustment 22.5 ok but wouldn't tick over smoothly. Tried the 25 nearly, but 27.5 pulls well and ticks over.
