if you have spark and not starting still check fuel lines and tank for debris or blockege in the fuell line, or the air filter may be too dirty fro air to sift thru try blowing they air cleaner out then replace and try startiing take the bell housing of the carb and scrub and spry with brake clean and replace . if no spark then try replaceing plug if that does not work trace back to where wire is.
