Hello everyone ... I'm having some issues with my Yamaha Slider , after I reinstalled the 19 mm carburator it doesn't start at cold even if i pull the chocke ... nothing but before with the 21 mm carb and also de 19 mm carb it started with Sport Air filter ... I've checked the carburateor it's set up properly and so the air filter I have no idea what can it be , i've also tried removing the Boost Bottle but nothing ... What should I do help me ?

Hi!

Check your sparkplug, if it's fouled you need to start your engine with full opened throttle, if drain pull choke and close the air inlet! (remove sport filter)


try to replace choke jet with larger

well i've forgot to mention when i remove the airfilter and put my hand in it's place it starts but why ? i don't understand the air it's fine when it starts it runs very well , my sparkplug is not covered fully and my sparkplug cap moves a bit but i think that doesn't matter ... maybe it's because of the extra oil what i put in the gasoline ?

how much?

That extra oil can be a problem . To much oil gets to spark plug...
