Have you checked to see your you're getting any spark? Is the plug you pulled out wet?Pull the plug and hold against the engine and kick it over and see if it sparks. Is the plug you pulled out wet? If it sparks, that part is OK. If it doesn't, and it's wet it's probably fouled, try another plug, or just hold it in your hand and kick, and see if you feel a tingle. If that works, get a new plug. If not, how is your battery? Do you have a multimeter? If not,go buy one. Your going to need one several times in your life, so it's a good thing to have around! You can get one for under $20.00, or down to about $5 at Harbor Freight! Go for the $20.00 ones if you'd like to keep it awhile! If the battery has dropped under 11V, you probably need a new one.
If the plug is wet, that's a good sign you are getting gas.
