No luck. I cleaned and dried the spark plug and cleaned the spark arrester screen. It won't even turn over. Nothing. I almost grabbed it and smacked it against a tree! I'll just go to the dealer on Monday.
Have you checked to see if you have any fire or spark at the plug? put your plug wire on your plug and with a pair of insulated pliers hold the plug against the top engine where you would normally screw the plug in, crank the engine and watch to see if there's any spark in the plug.

I don't have insulated pliers. I'm done with it. Thanks for your help though. The yard looks like crap. After just one season the high end trimmer won't work. I should have bought an Echo instead of spending a fortune on spark plugs.

Well if you want to send the trimmer my way I will gladly take it. I'll even pay shipping.

The cylinder is just full of gas take the plug out and flip the engine upside down and crank the hell out of it doin this while blowing compressed air in the spark plug hole helps alot too , id deff give it a try

If you just lay the spark plug next to the hole where you would insert the plug making sure it contacts metal and crank the engine you should see a spark in the plug. If there's no spark then you more than likely have an electrical problem.

I just had the same problem with my fs55r yesterday. Took a cut off saw and cut the screen off. No need for it IMO

I took it to the dealer today. He put some fresh gas in it and adjusted the revs with a screwdriver. Trimmer fixed and running great! And, free of charge.

Sometimes I hate Stihl, I have a chainsaw that I can't start. I take it to the dealer and within three pulls it fires right up. Then I get it home and it wont start. Take it back and he says the carb needs work. Remember it's a new saw. He fixes it and I take it home it starts and I cut one branch and shut it off. It won't start again so back it goes to the dealer. He says let me keep it a few days and we will see. I go across town to another dealer and buy an Echo. Go home and cut the rest of the stuff. Go back and pick up my Stihl and take it home, dealer said that they had messed up my carb during the work they did before and now it should work like new. It was new but never started. Now I have 2 chain saws that start and run. I still love my Echo because it has a primer bulb where the Stihl don't. Two cycles are made to make me mad and drive me crazy.

It turns out that there was a recall on my Stihl FS 110. The dealer replaced the part and now it's working like new. I wish we had discovered that – three visits to the dealer ago.

For future reference, all the Stihl products I have owned need only 1 pull stroke with the choke on. Then, it cranks 2nd pull with choke off. So when, all of a sudden it doesn't start that way, it has a problem and doesn't need to be flooded with gas. The only thing that needs adding to this post is many times you can spray sea foam or some other cleaner into the carb and clean it out. I spray my carbs as a regular maint when cleaning the filter and the exhaust screen or plug. I have an FS55R and it is balanced and light and I trim as many as 4 yards (over 2 acres) in the same location without stopping to rest. It is easy to take apart to work on. Only thing is if I take one completely apart, I leave the trigger lockout out when I reassemble it. That is an unnecessary safety device, which is hard to get back into place. I've got a few of those trigger lockouts just taking up space in a drawer.
