Hey
I'm new here and have been wrenching on turf equipment for over 30 years. I have replaced many carbs on the FS-90R trimmers, and I just went to replace another, they have changed the design to where you need a special tool to adjust. Stihl told me that the EPA directs them to now sell new carbs with Hi & LO jets in the closed setting. Therefor only a Stihl certified tech can make these adjustments. I can't even see the shape on the shank of the adjuster. Any thoughts on how/where to get this tool?

The latest Stihl carburetor adjustment tool that I've seen is a hex shape, thin-walled tool that fits over the needle in a similar way as the single & double "D" or the spline needles. Only Stihl dealers can order them, as of 8/14/2012, but that could change. EPA regulations are in place that prevent the average person from buying the current adjusting tools but they are on eBay except the latest Stihl tool. I understand that there is a steep fine if a person is caught selling these tools to non-certified (or some other word) individuals. I know there is someone on this forum that knows more about the legal side of this issue than me so maybe they will explain it more.

If caught selling the tool, the dealer can be fined $38,500, and the customer $3000 for mere procession. I have heard the the US EPA is walking into repair shops and doing inspections for non compliance. Possibly even doing sting operations like they do for alcohol purchases.

The EPA is monitoring E-bay sales and possibly go after the seller and the buyer.

I just don't understand it. If a homeowner or someone who is "not" knowledgeable attempts to adjust it, if it is too lean it will run hot and burn up. If it is too rich it will run rough and not have enough RPM's to even function as a line trimmer. So why does the EPA have a concern? Someone trying to tune not knowing what they're doing will eventually end up taking it to a pro anyway.

Because they don't want you to "richen it up" so it will run like it's supposed to. Their only concern is emissions. If you can richen it up, you put out more emissions. Liberal/Progressives don't like that.

Ah ha. "Thats why these machines don't last as long as they used to. I have noticed that all the new gas/oil mix engines' spark plugs are always white after much use. I have discovered that the spk plgs tell the health of the engine and they're all dry and white indicating A borderline leanish mixture. The purple color on the exhaust nuts and muffler even indicate running too hot/lean right off the show room floor.
If the EPA is so concerned about emissions, cow poop is the greatest offender of putting methane into the atmosphere.

They have already tried to tax farmers for the methane cows put out. It apparently went away.

M4 deep socket 1/4" drive apparently.

There's more than enough fossil fuels for all of us! :)
