Scooterotica

Hi guys , I really hope you can help me ,I bought a non running pk50xl and have been desperately trying to get it to run , I did have it running briefly but couldn't find its sweet spot regardless of how I adjusted the carb .

Here's a check list of what I've done , new cdi, new plug lead and cap , new spark plug , I've checked the stator ohms readings , I've checked the flywheel key way and crank key way , I've checked the timing on the stator plate , I've also stripped and cleaned the carb , new carb gasket ,the carb is a delorto 16/14 running 20 / 80 jets , ive fitted a new fuel line from the tap to the carb and mixed up some fresh fuel , fuel flow from tap is good ,I've also carried out a compression test which was also good .

For the last two weeks I've been trying to start the scoot ,the plug is a little wet and I've got a really good spark , I just can't understand why it won't fire ,it doesn't sound like it wants to fire any help or advice would be gratefully apricated thanks Kev.

hi,
maybe you have an airleak, worn seals or a blown gasket, try a leakdown test. also check the sealing pad in the crankcase, if its been damaged a popular fix is a reedvalve manifold, polini make them,stops your induction mix going straight back out of the carb instead of into the engine.
