I have a hopped up 66 Sears bluebadge that I'm trying to dial in:
Polini 130cc
Dell'orto PHBL 25 BS carb
Reed valve intake
Banana exhaust (some sort of Faco clone)
Electronic ignition
It starts and idles perfectly. 1/2 throttle to WOT it is a beast.
0 to 1/2 throttle is where it's uneven and sorta lurches. It feels like maybe it is starved for fuel.
Carb specs:
idle jet: 50
choke jet: 60
main jet: 92
slide: 30
atomizer: 266AQ
needle: D29 (clip at second notch from bottom)
Any suggestions?
From my research, I'm thinking I should focus on the needle and air/fuel mixture? Richen by moving the needle up by one notch?
Thanks in advance.
