Thank you for all your in depth informative videos on Chinese scooters I learn so much by watching your videos ...🙂👍 I do have a question maybe you can help me out with..? I have a gy6 150cc scooter ,I purchased it brand new in 2021 & here we are at the end of 2023 I'm experiencing misfires and surging at 25 mph in a way it's as if I'm flooding it or running out of gas..🤔..? Its been a week now and I'm puzzled I've swapped out carburetors and sparkplug. There are 2 things I know needs replacement #1 the fuel hose inner diameter is smaller then stock fuel hose. #2 I have a faulty ignition switch that needs replacement sometimes I have to jiggle the key before it could start Could you please help me diagnose my scooter by what I told you here or at least guide me in the right direction? I know it's hard not having the scooter infront of you to diagnose but from what I mentioned that it's doing what do you think can cause misfiring at higher rpms and surging the feeling of loosing power then catching power again in a quick second over and over unless I slow down to under 25 mph.....🤔...? Thanks Paul I sure could use your advice Happy Holidays buddy..🎄

Another question is, my SYM carburetor scooter over half year that engine does not working in Taiwan! After I push scooter start motor switch and then I got some situations as below: (1) engine cylinder pressure is 126psi (2) spark plug has flash (3) fuel tank does not working to push gasoline via fuel filter out? Do you have some idea to help to fix my breakdown SYM scooter here, thanks!
