going downhill from WOT to 0 throttle is like the worst nightmare. the engine braking is really scary. my vespa will become really wobbly, I have to release the throttle gently, otherwise I feel like im gonna die any minute.

U have to play with needle and slide then, idle jet is just for low revs with Real carbs. This guide is for SI CARBURETTORS :) which are cropped carbs as there is no needle

mista FreakMoPed well i have changed my pilot jet and it ran worse. it fouled my plug even if i open the air screw 5 turns out. it turns out that i need a richer slide cutaway. i've change it from 3.5 to 2.0 and it runs much better.

mista FreakMoPed my enggine jammed/seizing when it run about 80 km/h, what do u think 105 main jet for 4M (58.6 mm) piston? correct or too lean? i have watch all ur video about jetting, special for idle jet i whatch about 5 times to understand it, now i'm confiuse to pick the corrct number for main jet about my feul supply, i think no problem because when my speed under 80 km/h the engine look fine thanks for ur respon and all ur videos about vespa :D

thats an original cylinder isnt it? 105 way big enough. my tip is fuel supply. check tap and hose 50-55cm length and no edge in it
