It may be running very rich, make sure the air filter is clean, if ok. check the spark arrestor in the muffler outlet ( if fitted ) has not carboned up, if ok, check the exhaust port is not blocked with carbon.

I don't think this has the detail you need.
If it were me I'd visit my friendly neighborhood Husky chainsaw seller (not Big Box Store) and ask to look at the clutch cover with the brake installed (take a camera). I'd probably ask for a quote for their repair too. HTH

Your model is no longer sold. The seller will know what model replaced it and may be willing to explain the repair procedure for your saw you. Take the cover and loose parts with you.

SOURCE: 3 month old Husqvarna 235.

These machines have had issues with main bearing cages breaking up, this it turn scores the piston and snags the ring in, if there is a good spark and the plug is getting wet i woud whip the muffler off and take a look at the piston through the exhaust port.

It sounds like a warranty issue, up at the engine you have a centrifugal clutch bolted to the flywheel, as the engine speeds up the clutch expands and engages with the drum, this in turn rotates ans turns a flexible shaft within the tube, this engages into the gear box and turns the gears that turns the head, so i would say the flexible shaft is either slipping in the drum, or the tube or gearbox has moved out board so is now too short to engage into the drum.

The throttle trigger will not work on my 235e husqvarna


I'm guessing from the statement that it "will not work to increase speed" that you have been able to successfully start the chainsaw.
I have to look at this with the assumption that you haven't run a chain saw before, so bear with me if some of this is excessively simple.
If the throttle trigger does not move, something is jammed. The handle for the choke should automatically move to the retracted position when you pull on the throttle. If it doesn't, see if the trigger will move after you push the choke handle back in.
If the trigger moves in when you squeeze it but you don't hear any change in the engine sound then it's probable that the throttle wire has disconnected at the carburetor or at the handle.
Is the chain brake off? You need to pull it firmly back toward the upper handle for it to be disengaged. If the handle is forward it will lock the outer portion of the clutch. If you try to accelerate with it locked the engine will bog and not allow the chain to move.
Any of these conditions other than the chain brake will probably require some disassembly. Make sure you're confident that you've correctly reassembled everything if you're going to do it yourself.

How do I "reset" the brake?


If the chain brake is on and the sprocket cover is off the saw, they are a pain. You need to grip the clutch housing while turning backwards the tri-star \'cog\' in the inside of the sprocket cover. Ive done it in the past by holding it in place over the chain brake handle so the cog\'s line up and pulling the handle back in the off position. Failing that you might be successful using a pair of 90 degree circlip pliers.

Hi. I inherited a 1998 Husqvarna 265 rx. Got new plug and new fuel and it fires ok. Wouldn't stop so I added a washer under the 'earth' screw and it now stops. Problem is poor acceleration


To set the throttle, start by slackening the cross head screw securing the cable in the handle and pull completly out, now slacked the three allen headed screws securing the handle, twist the handle to the best position for your use ( at full throttle your thumb should not be straining ) now slacken the lower cross head screw and turn the silver clamp to tention the spring underneath, when correctly adjusted the throttle trigger should spring back to the idle position readily, now re fit the cable up through the clamp, turn the cable so as it is just about to open the carb throttle spindle, lock the cross head screw and test to make sure you are getting full throttle, if not slacken the screw and turn cable a little more.

I have seen some issues with these machines shearing the flywheel key ( it is an alloy key part of the flywheel ) if the key has sheared it will knock the timing out and will now require a new flywheel.

MOUNTFIELD R25M RIDE ON MOWER 2008, ONCE STARTED, WONT STOP, HELP PLEASE


On a lot of these small engines, the blade also acts as a kind of flywheel to help smooth out the power stoke from the engine.
result? no blade, or blade very loose, engine can be a right pain to start.
I'm not very familiar with the very new mountfields, but it sounds like a standard briggs engine.
If you follow the cable down from the dead mans handle, it will normally end somewhere on the side of the engine. When you pull the handle in, it pulls back a lever that frees a brake shoe, or sometimes a band, that acts against the flywheel. this mechnism stops the engine a bit quicker than wiothout it. it should also act on a small switch in the same area.
I often find that the switch isn't turning working as it should, and needs a gentle adjustment with a pair of pliers.
have a look at this first, but please tighten that blade up for safetys sake!!!!!!

I have a Husqvara 550 chainsaw. After chain popped and I put it back on, the chain won't move. It's on the gear and everything. Is there a brake or something preventing the chain from mov


There will be a chain brake, grab the brake handle and pull it firmly back to the top handle, this should didd engage the brake, if the chain has de railed the drive lonks will have burs on them which will make it tight in the bar, you need to file all these burs off.

The chainbrake should be activated when starting the chain saw. Activate the chain brakeby pushing the front hand guard forwards.b>Cold engine Start position, 1: Set the start/stop switch in the choke position by pulling thered control outward - upward.Decompression valve: Press the valve to reduce the pressure in the cylinder and makestarting easier. Once the machine has started the valve will automaticallyreturn to its original setting.Air purge: Press the air purge diaphragm repeatedly until fuel fills thediaphragm (at least 6 times). The diaphragm need not be completely filled.Grip the front handle with yourleft hand. Hold the chain saw on the ground by placing your right foot throughthe rear handle.Pull the starter handle, 4: Pull the starter handle with your right hand and pull out thestarter cord slowly until you feel a resistance (as the starter pawls engage)then pull firmly and rapidly until the engine fires.Push down the red choke control: As soon as the engine fires which can be heard through a"puff" sound, push down on the red choke control.Pull the starter handle (6): Keep on pulling the cord powerfully until the engine starts.
