Good evening together, short and short: Peugeot Trekker 50ccm from 2002 Purest hobbyist shop but drives like a new scooter Constant controls from the friend and helper belong meanwhile. To my problem: I had to change the cylinder head, then directly changed the piston. Did this together with a colleague who knows better, piston rings etc sit everything right Since that the scooter does not work any more. Compression I measured, is available enough. Carburettor I cleaned and disassembled several times About the E-starter the scooter only goes on when it is warm Ignition spark is there, candle also has a reasonable picture. With starting aid spray it goes on, but then goes out again after 5 seconds, although the petrol line is free. Even if I suck on the vacuum hose enough gasoline comes after. But unfortunately I can not get on the colleague and kicks me slowly. Before I play with the sales idea I do not want to give up the scooter. because of my little call for help from Lüdenscheid the currently probably worst city since the bridge blocking of the a45 What can it still be? Did I forget to check something? I am looking forward to an exchange
