Posting for reference as Ive just stripped the carb to see whats in there and am going to rejet as ive just swapped to a GT186 and TSR expansion exhaust.

So, Mugello 186 Mark 2, PHBH 30, Ram Air, 42mm AF Clubman on Series 2 Spanish Lambretta with 16.5 stone of me!

Main Jet 125
Atomiser AV266 (remember AV is richer than AS)
Slide 40
Needle X13 (top clip i.e. weakest)
Pilot / idle jet 50
Choke jet 70
Float 8.

One thing I never bothered to change was the Float needle valve, many seem to recommend doing so as on high revving motors I believe it can relieve the possibility of fuel starvation, ie the engines using up fuel quicker than gravity can deliver it to the float bowl.
Im about to look into this as my new engines a reedvalve and expansion so Ill do some asking here and elsewhere and come back and edit here if i do change it and why.
