[QUOTE="dirt bike dave, post: 1430877, member: 18302"] Buy a new spark plug and put it in. My old CR used an NGK BR8ES, but check to make sure that is right for you. Pump premium fuel should be fine. Use that instead of regular octane. Some bikes are hard starters. With the new spark plug in, here is a starting drill that works on most two strokes: Turn the gas and the choke on and lay the bike on its side for 5 - 10 seconds. You want gas running strongly out the overflow tubes to the carb. Stand the bike up. Keep the throttle closed. Move the kickstarter GENTLY though its stroke twice, to prime the cylinder. Then find top dead center by gently pushing the kickstarter until you feel the the compression get harder. Just as the compression begins to ease, you are at top dead center. (Finding TDC will let the piston get up maximum speed before the next compression stroke) Return the kick starter to the top and KICK as hard as you can (careful not to bang your shin on the foot peg). For most bikes, DO NOT turn the throttle open AT ALL when cold. You can even put your right hand on crossbar or master cylinder to prevent you from twisting the throttle. If no go, find TDC and try again. Some bikes do want a TINY bit of throttle on cold start (like 1/16 open, no more than 1/8 open). As mentioned before, bad gas, worn rings or reeds can make cold starting very difficult, even if you master the drill. Most two strokes will smoke a bunch on cold start, but the smoke should get much less after you get it up to operating temperature. Good luck! [/QUOTE]
