FAQs

To see what Stihl model saws we offer a Bark Box for, please check the drop down box on the Bark Box product page. If your model is not listed, it is not compatible with a Bark Box. In order for a Bark Box to be compatible, a two-piece muffler is required. Most often, if your saw model is not listed, it is because the saw has a one-piece muffler. The second reason is that the muffler on the saw is too small. In that case, we recommend opening up the stock hole.

At this time our focus is on developing and putting into market the highest quality aftermarket products. For that reason, we are not currently able to offer chainsaw repair or modification services.

Air Cleaner System

Installation instructions are included in each air filter package. You do need to oil and clean the filter. We strongly recommend Bel Ray Foam Filter Oil which can be purchased most conveniently on Amazon. Spray oils will not penetrate the foam sufficiently.

When applying the Bel Ray Foam Filter Oil, what we do is saturate the filter completely and then we squeeze out all the excess oil. This lets the oil penetrate into the filter. When you're done you could dab the outside with a paper towel if you have any wet spots to make it perfectly even. We've found through experience that this is the best way to protect from anything getting through.

Bark Box

Remove the four bolts holding on the front plate of your current muffler cover. Place the Bark Box in place of your previous cover and reinstall the four bolts. *Note that anytime you open up the muffler, you’ll want to add more fuel. If your saw is Mtronic, it will self-adjust. If you have a carbureted saw, you’ll want to make manual adjustments. See Fuel Adjustment Tips below.

461 Bark Box – Remove the carb limiters, grind off the tabs and reinstall. Then, remove the four bolts holding on the front plate of your current muffler cover. Bend over the screen tabs. Place the Bark Box in place of your previous cover and reinstall the four bolts. You’ll want to adjust your carb settings per the recommendations below.

Fuel Adjustment Recommendations at SEA LEVEL

For turning up the fuel on the manual saws, there are three screws in the carburetor. Usually two that are side by side and one that is above or below. The two that are closest together are your high and low fuel adjustments. The other is idle. On your low screw, which is always the closest screw to the cylinder, you turn counterclockwise for more fuel and clockwise for less fuel. This is the same for the high screw. If you have limiter caps on the end of the screws, you can remove them by running a screw into the middle of them and pulling them out with a set of pliers. After you remove them, you can grind off the small tab and push them back onto the screw. After this you will have full adjustment. After this go clockwise until it stops and call that zero. Then count your carb turns going counterclockwise. The carb settings that we recommend are 1 & 1/8 to 1 & 1/4 turn on the low and 1 turn on the high (this is at sea level and a good place to start on settings), then reset the idle. After that, watch your spark screens or your plug for color. It should look light brown like a cardboard box.

Faller’s Suspension Kit

To install the rubber buffers, the first thing to do is remove the air cleaner cover and air cleaner. There is a spring on the clutch side, remove the top bolt. Remove the handle bars. Once the handlebar is removed, lay the saw on the starter side, clutch side toward the ceiling. There is a bolt above the bottom dog bolt. It is countersunk into the case. Remove that bolt. That will allow the front mount to drop out. Once you put the spring on and the front mount, you can reattach that to the case. Now you should be able to grab the tank and swing it away from the case allowing you to get to the rear mounts.

500 Kit – Follow the directions as written above. The spring will simply screw onto the front mount.

Universal Exhaust Power Port

Identify a flat spot on your current muffler that fits the size port that you’ve ordered. You hold it into the position that you want and then take something sharp like a nail and scratch the inside of the port onto the muffler. Then take a drill bit and drill a hole and dremel out to the line you've etched. Then you can either screw it on or weld it on.

Anytime you open up the muffler it's a good thing as far as horsepower gains and cooling cylinder temperatures. Whenever you muffler mod it's a good idea to add some fuel to your carb settings. See our Fuel Adjustment recommendations above.

261 Universal Port - The universal port fits on the starter side of your muffler. You hold it into the position that you want and then take something sharp like a nail and scratch the inside of the port onto the muffler. Then take a drill bit and drill a hole and dremel out to the line you've etched. Then you can either screw it on or weld it on.
