According to Stihl's engine service manuals, when the engine has no spark or a dramatic, sudden loss in power, the problem could lie in the ignition system. The ignition system ignites the fuel in the engine for proper combustion. When the spark isn't firing correctly, an influx of gas can bog the engine down or cause it to not start at all. Since you are dealing with potentially lethal high voltage, extreme caution is advised and safety gear should be worn at all times.
first Slide the rubber spark plug connector off of the spark plug. On most Stihl's this can be accessed from the top of the engine, underneath the chain brake handle. Unscrew the air filter cover and remove it, if you can't see it on top of the engine
then Insert the socket wrench onto the spark plug and remove it from the engine. Discard the old spark plug and replace it with a new, identical spark plug, which will be recommended in your operator's manual. Make sure the spark plug is gapped according to your manual's specifications or else the engine won't start.
after that Turn the ignition switch to the "On" position. Insert the spark plug into the rubber connector. Make sure the chain brake is disengaged by pulling back on the black chain brake handle, which runs atop the saw's engine.
Hold the rubber plug and spark plug, with gloved hands, about 1 to 2 centimeters from a metal point on the engine block. Wipe any flammable gas or oil from the metal spot on the engine with the rag. Tug on the starter cord and look for a blue spark across the "hex" part of the spark plug,Check to be sure the wires leading to the "On-Off" switch aren't tangled or touching a metal point on the engine if there is no spark, Replace any wires if they are damaged or corroded

Stihl fs250 blowing fuel out carburetor but plug is dry
It is quite unusual for them to exude fuel from the carb, if somebody has removed the carb at some time it is possible they have re connected the fuel hoses incorrectly, it is important to remember that the fuel bubble is a purge not a primer, so it pulls full from the carb into the bulb and back to tank, if the hoses are incorrectly assembled you can push fuel into the carb, this would cause fuel to exude from the carb.
