Bilt Tb425cs 26cc 4 – Cycle Curved – Shaft Gas Trimmer with…

Looks like the shaft keeper has broken. When I look down the attachment hole, the head has popped up and doesn’t move. When I push it back down it spins. This will require some disassembly to fix.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

If the drive cable is broken or detached, the trimmer head will not spin. To inspect the drive cable, remove the engine assembly from the shaft and look to see if the cable is in its proper place. Reinstall the cable if it has slipped from its place. If the cable is damaged or broken, it should be replaced altogether.
The clutch engages the clutch pads to spin the trimmer head. If the clutch assembly is defective, the clutch will not disengage the clutch pads, and the trimmer head will continue to spin, even at low speeds. If the clutch is defective, replace it.
If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.
When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
Checking for debris or damaged blades: Visually inspect the blades and confirm there is no debris stopping the blades from moving. If there is debris ensure the machine is powered off when removing any blockages. Check the blades for any damage as a damaged cutting blade could cause the machine to stop working.
The Blades Need Oiling

The friction wears the blade and produces heat that will force your clipper to work harder, causing the blade to stop cutting. To avoid this, you should oil your blades at least after every use. This will also avoid the chance of the blade corroding, which can happen surprisingly fast.

If the drive shaft is broken, the string trimmer head won`t spin. The drive shaft is not repairableā€”if the drive shaft is broken, you must replace it. Need help finding your model number? If the threads on the drive shaft are stripped, the trimmer head will not stay on the shaft.
If the engine will idle but dies at full throttle the main jet in the carburetor may be plugged. You can repair a plugged main jet by cleaning it, replacing the jet, or replacing the carburetor. If you choose to clean or replace the main jet, you will also want to clean the rest of the carburetor.
If the engine is not revving up and cuts out before you reach higher revs then you need to do the following checks: Fuel: Make sure it is fresh and correctly mixed (see `Starting Issues`). Air filter: Make sure it is clean and unclogged. Fuel cap: Make sure it`s hand-tight.
The choke, a butterfly valve, reduces the intake of air and allows a fuel-rich charge to be drawn into the cylinders when a cold engine is started. As the engine warms up, the choke is gradually opened either by hand or automatically by heat- and engine-speed-responsiveā€¦
Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine.
Spin Direction

Just as a circular saw needs to eject sawdust as it works, a trimmer needs to eject debris from its cut path. If your trimmer spins counter clockwise, it ejects material from the left side of the tool and cuts best with the right side.

For best operation and longer blade life, lubricate the hedge trimmer blade with a lightweight machine oil before and after each use.
A hair trimmer is designed for styling shorter hair, including facial and body hair. They feature smaller blades than clippers, allowing them to cut closer to the skin.
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the string trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance.
Charge the battery.

Detach the trimming head and switch on the trimmer. Is the motor running and pin rotating, then both the battery and handle are okay. If not, the battery of the trimmer has run out. Reattach the head to the trimmer and recharge the nose hair trimmer.

It is possible that your shaver does not turn on or move because it is dirty. There can be hair or dirt particles stuck inside it, causing the shaving heads to be blocked. To fix this problem, properly clean your shaver. If possible, remove the shaving head and clean your shaver from the inside as well.
The most common reason for the cord refusing to rewind is a broken or worn out recoil spring. This tiny spring hooks onto the pulley and is stretched out when you pull the cord; when you let go the spring is meant to snap back to its original position.

25 hp kolhler won’t stay running
ANSWER : Check fuel filter, it may be clogged, if so replace

My mower will start but won't stay running – Toro LX466 22HP Lawn Tractor 13RT61RH244
ANSWER : I am going to respond 2 times to this post. The first reply will be generic things to check.
First off check the oil level and make sure it is serviced to full.
If your having a lack of fuel (runing lean) you will need to check fuel flow at the carb fuel mainfold. It should fill a spray paint can lid in less than 10 seconds but teting flow rated of the main fuel line. If you have poor flow here… you need to check the fuel filter and the fuel tank outlet port for obstructions.

Good Fuel flow still shutting off…. remove the carb float bow and clean the debris from the bow’ and the treaded area where the fuel solenoid mounts Additionally you will have to again remove the main fuel line and spray carb cleaner in the float needle area to flush out any debris through the fuel hose connection.

For the second response I need to know which engine is installed on your mower by MODEL number if you can locate it. (there are 3 engines) At least try to find the engine model number. If you can not locate it Brand and HP of the engine (I assume 22 hp) Thanks for choosing FixYa,

Lawn scarifier motor runs slow than starts to smoke

Toro 149cc Lawn Mower Won't Start – Toro Lawn Mower With Toro Power Tools
ANSWER : Bad carburetor your old fuel jammed up the jet so it won’t get fuel and if it does it will start and shut off So replace the carb or try to clean the jet and run non oxy fuel only

Mower won’t start
ANSWER : This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.

Hope it helps.

Serviced my riding lawnmower runs great. but when I put in drive it dies out. Also when I engage blades it dies out. No problems last summer. It won,t stay running when I do these two steps
ANSWER : Probably the seat safety switch. If it’s not activated (from your weight on the seat) the engine is killed when you put it in gear, or engage the blades. Lift up the seat and check the switch – wires on tight? switch tightly mounted? You can take the switch out and tape it in the pushed-in position to test things. If that doesn’t let the mower run, the switch itself is probably bad, but it could also be a connector that knocked loose when you serviced the mower. Check wires and connectors. Good luck!

…the motor runs but head won’t move.
ANSWER : The head drive is probably craked or stripped or the driver is broke, to check this, remove the head and inspect, these replacement parts normally are pretty cheap.

My mower is about 2 months old. Haven’t had any issues until last night. I think I ran out of gas (maybe not, it was getting dark). I filled it up, and won’t stay running. Barely starts unless it is tilted way back (like handle on the ground all the way back), then it runs like a champ. If it is level, it will barely run until it dies. This is on concrete, and there is nothing underneath.
ANSWER : Hello,It sounds like there is sediment in the carb bowl. Remove the gas line from the carb and plug the line with a phillips head screwdriver. Remove the bolt in the bottom of the bowl and carefully tap on the bowl to loosen it without damaging the rubber gasket. Clean the bowl, and blow the ports in the bolt out. Raise and lower the float inside the bowl space to make sure that it is working freely. Re-assemble making sure to seat the rubber gasket properly. If there is sediment in the bowl, you might also consider an inexpensive in-line gas filter ($6 at Lowe’s, etc.).Best regards,–W/D–
