Question: Troy-Bilt TB20CS Starter Problem

Keith34

I have to hold the speed lever to get my trimmer to start. Is this a bad carburetor problem?
Hi Keith34 Not necessarily. The procedure for starting a COLD 2-stroke is hit primer bulb 4 or 5 times...choke fully closed...and throttle trigger wide open. Pull starter cord. After it pops, move choke to 1/2 way closed ......throttle still open...and it should start running. Then after about a 10 second or so warm up, open choke completely for max air flow. If it does not start in this fashion, post back for more tips, diagnosis, and help.
The majority of problems with THESE machines is normally carburetor or fuel related though.
It ran for a bit and I got my trimming done but now I'm using it again and it wont start at all.
Do you sell the tool to adjust the carburetor speed? (The two screws to adjust speed?)
Hi Keith34 I am not a salesperson, nor do I work here. I come on here to help others such as yourself fix their own equipment. The little carbs have 4 types of Mixture screws: 1.(most common) Splined Head...find these on ebay 2. Pac Man Head 3. D-Head 4.Double-D Head Check on ebay for best deal and lowest prices.

Question: Remove Cutting Head

lindsaylsu2

Hello, How do I remove the cutting head? That's the part that stays connected to the shaft. It's NOT the part that you spool the line in. I believe it's figure 18 in the above diagram.
Hi lindsaylsu2. Did you ever get an answer to your problem? I have the same difficulty and cannot find anyone who knows how to take this part off of the weed eater.
WJA
Hello lindsaylsu2,

You will have to remove the 791-610660 retainer, up inside of the outer spool. You may heed some needle nose pliers to get a hold of it. Don't worry about damaging it. When you order the new 753-04284 outer spool it comes with a new retainer.

Question: Spring Assit On A Troy Bilt

jmccane

I have a tb20cs Troy bilt gas trimmer with a spring assist. the pull rope just pulls and a clanking sound is heard. It does not try to start the engine. How do I repair this.
WJA
Hello jmccane,

I'm thinking it could be a couple of parts that might be worn or broken. Take a look at the recoil pulley, make sure the teeth on it aren't worn or broken. Also look at the flywheel assembly, look at the dogs on it to see if they are damaged.

Hope this helps,
WJA
