Look, I'm no bike mechanic.....but I've learned a lot here on this site......enough to work on my own bike and before you do ANYTHING please, please get a manual for your bike. Really man, no offense, but if you don't know what plug to run or what/where the jets are...... I don't think you should go to pullin' the carb just yet. If the bike was running fine and you fouled the plug (which could happen simply from ridding too slow on a 2 stroke), then you changed the plug and it wouldn't run.........I'd start with the plug. Where did you get the plug ? You can google your bike and find out what plug you need and the correct gap. It's important that you use the correct plug. If the plug is too big you'll knock a hole in the piston, too small - no fire. Also make sure it's gapped correctly or even if it's the right plug, it won't work right. Good luck bro !!!!!
