Is it possible the carb is running too rich? Flooding the cylinder before the motor can fire...
If its stock thn that would be last place to look.

Is it possible you spun the rings? The gap in the rings (for installation) need to be in a specific position to one another to prevent too much blow by. Could be another source of low compression.

I've changed the jet in my carb and opened the exhaust to match the dual boost bottle kit I installed. I'm running great except...
After long run times, (I use my bike to commute) the exess unburned fuel carmelizes and coats the plug. After I've ridden 14 miles, what ever stop I make has to be quick. Gotta get the motor fired again before it cools off or its a fight to start.
I've yet to add a piece of sand paper and a 3/4" socket to my tool bag, so fight it is until I get the jet changed to a smaller one.

What does this mean and how do i Fix it? How do I know if it is running to rich and also the oil/gas mix was 8oz:1gallon as suggested for break in period. Looking to find out any options to resolve this and get it started again.

Oh. forgot to add that I looked at the piston and the rings appear to be fine. Also torqued the head bolts at 12ft/lb per another post. And checked the muffler. Even went so far as to remove it all together. Very loud pops occurred without it. Still no start. Seems black fuel is dripping from the pipe and/or pipe hole so thinking fuel must be getting to the cylinder. getting puddles of black fuel.

Could be the break in mixture is too much oil for the plug to burn. That would explain the black...

I haven't had my 2 stroke apart yet. I'm going what I know about 4 stroke engines. There can be as many as 4 rings on a piston to keep the compression/combustion in the cylinder and not blow by in to the crank case. (4 rings is a really high compression engine) the gaps in the rings (if there is more than one) are usually 180 degrees from one another. So what ever gets past the top ring, very litle gets past the next. If the ring gaps are less than 90 degrees from each other, that can ge a source of low compression.

Also if you search youtube for "how to diagnose magneto loop" you'll find the specs for the ohm resistance ratings you should get from the loop and coil. You can confirm or deny an electrical failure as failure to start cause.

You got carb, compression, and electrical to look at. These engines are not to complicated but tend to act like a computerized paper wieght when trying to diagnose them...only other thing I can think of is a broken or loose wire...
