I have a 80 cc china girl its runs fine, still breaking it in. I have about 60 miles on it, I got rid of the original spark plug and got a ngk, I'm not sure of the numbers but I got it from our atv shop they seen the bike and sold me the plug, but now I pedal to start and some times when I release the clutch the back tire skids second time it fires up, any ideas?
getting hard to start

It does this every time the same ? only since plug change ?
Doesn't really 'add' up ... pretty slim chance of a spark plug being the reason for a symptom like that // actually , a 'symptom' like that doesn''t really "add' up ... I know that with most of these motors it seems that after being parked from riding . the next time the bike is used , you have too , almost always , kind of 'break' the drive line 'free' .. by this I mean that these little motors seem too need a little 'bump' too make sure that everything is turning freely before attempting too start them after sitting idle for any length of time .. so before you start it .. just rol forward and pop the clutch just to make sure that all is operating freely .. you will most likely hear a little bit of a 'click' as the wheel first breaks loose to start turning . If you get in the practice of this I think you will find the 1st 'skid' try will no longer be present.

That's a good sign, it means your compression's increasing: breaking-in.
I can actually walk start my engine; I have to since my pedal-chain is missing. To avoid what you've described, with the clutch engaged, I will gently roll the bike back until the engine-resistance prevents the wheel from turning, then I pull the clutch, start rolling forward, and pop the clutch. This assures that the engine turns-over during the lowest compression of its cycle and gives the flywheel enough momentum to quickly compress and fire.

Sounds normal for an engine that is breaking in properly. The rings are seating and the compression is going up. Pedal faster. Like was said above, 10 MPH is about the minimum you want to be before engaging the clutch. Also 10 is about the minimum speed you want to go with the clutch engaged. Anything slower, disengage and use the pedals.
