finaly after many questions and help from some of this board great vespa expert i did it!!!
i grind the metal a little for the electric start.i was afraid to grind the metal too much and enter one of the transfers but i did it fine.
i did n’t managed to locate the peg of the second ring in it was a little messy to slide the piston to the cilynder,if it came in there is no way i missed the peg right???
for start i change the main jet to 125 and drill a 5 mm hole in the air filter as it says in the instructions came with the kit.
i adjusted the ignition in the center between A to LT as one of u in this board adviced me.
the engine is working fine,the idle is ok.what should i do next?i run it very slow so i guess the main jet didn’t get to action yet,how do i know if i need to replace to a smaller jet or stay with this jet?
hope to get some good advices
