Hey bigpat,

Of all the issues your buggy could have, ignition timing is probably the least likely.

Is yours the water cooled CVT engine? If so, that is nothing more than a scooter engine with a reversing hub bolted on where a scooter rear wheel would go. There will likely be tons of info online from scooter enthusiasts that will point you in the right direction. That's how we learned to modify our Gio 150 Monster quad (it uses a GY6 scooter engine).

Please tell us what you've done so far, and perhaps we can offer some guidance.

Cheers!

Valve adjustment procedure, but it shows the timing marks.
