2006 GG125 cut out a few times last season and was difficult to start, wouldnt start from a kick but would bump start down a hill or being pushed. It was then fine for quite a while but a few weekends ago after a practice session it refused to start again. Ive got a spark and fuel, although not sure how bright the spark should be (the plug not me lol)

Should I be checking the stator? How and where???

Any help appreciated guys

Start by taking the carb off and cleaning it, refit then try again, not saying it's gonna go but it's a process of elimination

What color did the spark plug electrode have when removing it?

Ok, so after some diagnostics.....

I had a strong blue spark, what felt like normal compression, fuel to the carb, fuel in the float chamber.....still no starting. I suspected piston rings so i then poured a cap full of fuel into the spark plug hole and replaced the plug, kicked her over and she ran on the fuel in the cylinder.

So it's not likely to be rings.

I then removed the carb and stripped it completely, cleaned it and fitted back on the bike. I did notice on removal that the fuel input was positioned straight upright, which could have put the fuel line under some undue tension. When i re-fitted it I adjusted the fuel input so that the fuel line was not under any tension or not at right angles.

Fuel on, choke on, 3 kicks and wayhay!!! Back to normal!
