Question about Troy Bilt Tb70ss Gas Trimmer

Troy-Built TB70SS, 1 year old, will not start even after carb cleaning

My Troy-Built TB70SS will not start. Bought new in 2008. When cut off choke would have to be set in order for it to restart. Even when new it would sometimes stall when gas was applied to increase rpm so that it could cut. Carb has been removed for cleaning, new spark plug. Small fuel jets may have not been cleaned. Fuel can be seen in lines. Still it will not start. Plug has fuel on it when removed and inspected.

Check to see that the kill button is not stuck in the contacting position, and if it is, try to get it unstuck. WD40 should help. if it's not, then disconnect the kill wires. now try starting it. if it still doesnt start, then the spark generator is bad. if this is the case, you'll need a new trimmer, or have a small engine mechanic replace the generator. i think its called the coil, not sure at the moment it's 4:00 am for me. anyways, whichever is cheaper is best choice.

If you rebuilt the carb did you turn any of the screws on the carb while cleaning or take out, you might have just the low idle screw closed a little to much open half turn and see what happens. If you look at the carb where needle screws are located on the side,if you have two screws it will be stamped with an " L " and?or an " H " next to each screw. If you only have one screw then turn that one, to left to get more fuel. Good Luck...

We have a Troy-Built 21 Inch Self Propelled Mower we bought in August of 2010. We used it 2 times. This year it will not start. It tries then dies as soon as it even makes a starting noise. The problem...


Gas these days has shelf life of about 20 days. The ethanol. Drain old gas clean plug and then try. Also be sure air filter is clean. If that dooesnt take care of it u may have a fuel jet clogged do to old gas or a float sticking in up position. This would require you to remove carb and clean with spray carb cleaner. Also look for obstrucction.

My troy built starts but will not speed up enough to use even after it warms up. It is 2 years old but only has 3-4 hours of use on it . Can you help me?


Is it 2 cycle or 4 cycle? Meaning, does it take plain gas, or mixed gas?

Clean the plug, clean the carb with either choke cleaner (4 cycle) or wd-40 (2 cycle) by spraying it into the choke hole after you take off the air filter.

You may also want to spray some of the choke cleaner or wd-40 into the gas tank with the gas to help clean out the whole fuel system.

Only use choke cleaner for 4-cycle regular gas units. For mixed gas, use wd-40 in place of choke cleaner.

Try to start it and then go back and forth from half choke to full choke until it starts picking up.

Troy built weedeater 70ss gas engine will not run


The needle and seat (esp. the needle) meter the amount of gas/oil that is being allowed into the metering chamber of the carb for use by the engine. Your problem does seem fuel related. These carbs are very temperamental and scare most folks. A guide to how they work can be found here: www.zamacarb.com/pdfs/TechGuide_2007.pdf
This will give you an understanding of what exactly you are dealing with. You may only require a diaghram kit or rebuild kit to get the carb back to the functionality it was designed for. That info can be found here once you know your carbs exact model number.
http://www.m-and-d.com/zama_carburetor.html
A troubleshooting guide for these carbs is included in the first pdf file, look it over maybe and see what you think. Post back maybe later after going to school (doesn't hurt to learn how they work). We will be here. I know you want to use this machine (its the growing season) but there are so many things that can be wrong that it needs to be narrowed down...sounds like fuel starvation and just may need to clean the inside of the carb with something like the brake parts cleaner spray. It is non-flammable and doesn't damage the sensitive parts inside these carburetors the way ehanol and harsh carb/chokle sprays and strong solvents due...NEVER soak these carbs in a "Gunk style" carb cleaning tank....it will seriously damage sensitive internal parts and check valves!

My Troy-Bilt TB70SS starts fine,but it will only rotate the spool if it`s in half choke.If i put it on run it stops rotating.


Hey... I have the same problem. It will start if I put in on #1, then it will continue to run if I put it on #2... but will eventually stop. It likes to idle between #1 and #2... but it will not run full power on any speed. Relativey brand new. Piece of junk and I will never buy a Troy Built anything even again!

Sorry I could not help with your problem. I can usually fix anything, but this thing is a piece of ****!

Weed eater won't run


Sounds like you may just have a dirty carburetor.

Youwill need to disassemble the carburetor and spray with carb.cleaner.Make sure the small screen is free of debris. (Should be able to seedaylight through it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance, just let me know.

I have a Troy Bilt weed eater and am having a problem. It starts with the choke on, but it will not run with the choke off.


Ths problem is possibly indicating the need for a new fuel pump diaghram in the Zama carburetor. A carb rebuild kit installed correctly should alleviate this problem and greatly improve throttle response on the unit. The ethanol in the fuel nowadays plays havoc on carb parts and they become less flexible and more brittle, thus affecting performance and leading to problems with throttle response and carburetor functions such as this.
