Question about Troy Bilt Tb70ss Gas Trimmer

1 Answer

Troy built weedeater 70ss gas engine will not run

Bought new gaskets for Troy built 70ss gas engine. Installed gaskets but no results. Weedeater runs while choke is on, then runs for five seconds after choke and dies. Seat and needle were not replaced. Would that make a difference? Have taken carburator apart several times, cleaned everything, replaced lines. What is next? Used new gas and oil mixture. Weed eater/trimmer is about 2 years old.
Thank you for any help you can give.

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.

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!

Runs a few seconds then dies, new gas lines new filter takes carb apart and cleaned it new gas


Bill it sounds like you havn\'t put the carb back together properly. The gaskets need to be done correctly for the engine to suck fuel through. It runs due to limited amount of fuel getting through.

Weedeater gas edger won't start!!!!!!!!!


yes, there is a spark module, but it's highly unlikely that two would have a bad module - more than likely, it is your gas mix. it must be fresh for the engine to run. the gas we have today will go bad in about a month and a half. if you happen to live in an area that has E85, forget it. small engines will not run very long, if at all on this junk. in some areas, you can get gas without alcohol, but it can only be used for lawn & garden equipment. it's expensive, but your engines will run

I have a Troy-Bilt 31cc 2-Cycle Gas Powered that doesn't start


Coil bad or wire to coil bad. I tell everyone what Ill tell you,when it comes to small engines,troy bilt,poulan,weedeater brand all JUNK,JUNK JUNK! Theyre made cheap,not built to last,theyre throwaways. Carbs are made in china. If youre ever in walmart next time go back to the garden section and pick up a weedeater or poulan brand chainsaw or trimmer. Look at the package good and look at the factory life expactancy. Its not in months,not even days,but in hours. If I was you I would tell myself NO MORE! I would buy a dolmar or stihl,pay the extray,cause you wont be aggrevated in the long run. P.S. Dolmar offers a 100% coverage for ONE YEAR on all equipement.

Weed eater will idle but shutdown upon giving gas


Cleaning the screen on the muffler will help but the muffler itself is what needs burned out. This can be done with a fire or a torch. Let the muffler cool on it's own as use of water can warp it. Parts can usually be purchased at any small engine repair shop that represents Mtd. That's who make the weed eater.

Stihl weed eater runs 2min. then stop


Stihl weedeater was running and stopped suddenly. Put in a new fuel filter and cleaner air filter with soap and water. Checked spark plug and it appeared fine. Started the weedeater, ran for a second or so and stopped. Spark plug wasn't gas fouled. Could it be the carburetor needing new diaphram gasket and spring.

Weedeater want stay running


My guess is that your fuel lines and/or primer bulb has a crack or hole in them. Check these out and let me know the results. I can also recommend a great place to get these from if they are bad. Hope this helps.
