before a few days I instal Big Bore Cylinder Kit (80ccm) by Malossi and alsow I instal Power Cam from same producer to my Vespa S50 4V 4T. I did it slowly ... no hurrying, each part of this "puzzle" was check before instal. Everything goes slightly, piston rings "clic" nice, tightening of all component on correct Nm, applycation of new bearing to camshaft was smooth ... and in my mind I telling "that will be nice tune up". After asembly I tryed to start engine. Rear wheel slowly spining and I could hear only starter but nothing more.
Starter works well, after a few attempts I smel gasoline so fuel supply should be OK too, carb is ok and all hoses are connected, spark plug is OK but dry. (should had be wet from gasoline after a few attempts to start???) What about ignition ... could it be that problem ?
Thanks for all opinions and replies.
