20 Most Recent Troy -Bilt String Trimmer/Blower Attachment #41AJBT-C966 Questions & Answers

I assume you are talking about the oiler for the chain and if so it sounds as if the oiler is either blocked with chips or it is broke. You can go to ereplacementparts.com and put the model and model number in and it will show a drawing of the saw and you can then fix the problem.

Check out the drive unit from the head of the motor down to the trimmer head it may have a problem.

Sounds like either the switch for the blades is not shutting off the power to the electric clutch or the clutch itself is not disengaging. I would shut the mower off and unplug the wire to the electric clutch and then start the mower and make sure the blades do not turn you may have the belt for the blades on the wrong pulley and it might be causing the blades to turn. Hope this helps.

When the primer bulb sticks down either the cause can be
1. Fuel line is clogged
2. Fuel shut off is in the OFF position (if installed)
3. Fuel tank pick up tube is folded over or clogged. (inside the fuel tank)

I checked this model number: 41AJBT-C966 and it did not cross exactly. I found several C966 diagrams but they all have different engines from 25cc all the way to 65cc. If you need more help it will help me help you if you know your engine model number (i.e TB25 TB42 etc.) and would post it in your response.

Thanks for using FixYa.

yes make sure the open ends do not line up, stagger them in 3rd's oil well before you put the piston in the ring compressor. Make sure you have the piston "Front mark" orientated properly before instalation.

No shouldn't affect that. Try using a mixture of super glue and baking soda smear it on and press into crack I have had good luck with this when many commercial products failed.

You need to clean the carb. or you may need to buy a carb. kit. But do a cleaning on it first. If you need tips on how to best do this, just let me know. Also check the fuel lines for cracks. As they age, they become brittle.

The primer bulb can be replaced without replacing the whole assembly. If you have any questions on how to do this let me know.

It sounds like you are winding the line in the wrong direction. You should wind the line in the opposite direction that the head spins during operation.

Good Luck!

Jim

You can replace just the bulb...

hello,you can kindly download your troy bilt manual from the link below and also instruction on how to use it.

wish you good luck,

take care.

Prime and watch the fuel move up to the carb. This is the fuel line and it should be long. Make sure it goes to the bottom of the fuel tank.

It sounds like your carburetor needs a good cleaning. You must disassemble the carb., clean all the ports with a small Den Tech Brush, (used for cleaning between teeth). They are very small and perfect for this job. You will also want to clean the small screen in the carb. It may be so clogged that it may need to be replaced. If this is the case, you will need a carb.kit for your Troybilt Trimmer; it comes with small parts and gaskets. (It will come with some gaskets that you will not need.) Replace all old parts with the new ones. This should fix your problem.

The model number for your post is for the blower attachment. Can you pass the model number of the upper assembly please so we can better help you. Thanks

I am going to go out on a limb here.. Most of these troy-built trimmers use this carb with primer bulb.

What usually happens to them is the primer bulb on the bottom of the carb gets a pin-hole in it and then air is drawn into the carb vs fuel from the tank.

You can try to get just a primer bulb at your local lawn mower parts supply. You may just have to bite the bullet and replace the whole carb.

Sounds like you have fuel leaked into the cylinder. Remove the spark plug, empty it out, pull the rope a few times to force out the excess fuel, dry the plug off and put it back in. Don't put the choke on, open the throttle all the way up, and she should start. Remember, liquid doesn't compress, and sometimes changes in temperature or atmospheric pressure can push fuel through the system and into the cylinder.
