Wont run when you pick it up or give it gas

I have a troy bilt weedeater and it starts fine, but when you squeeze the trigger it dies. You can squeeze a little and it will still run until you pick it up and then it dies.

Troy-Bilt Hand-Held Blower dies when warm and throttle wide open

Good job.
A couple more things:
  • Replace fuel filter, it's in the gas tank
  • Check and clean the Spark Arrestor screen at muffler, when they plug up, it's a major restriction to exhaust gas flow
  • And check and adjust High/Low screws at carburetor, video attached.
  • And clean or install rebuild kit for carburetor
Good luck...

Tb144 troy bilt tiller, starts and idles fine, after it warms up, you can give it gas and it runs fine. when you let off the gas and return to a idle, then try to give it gas agian, it will die. then it...


Sounds like you have a dirty gas problem.
Empty the tank and remove it, clean it out and before refilling filter the gas to remove contaminants.
If this fails the problem is the carburator.
Remove it and disassemble and allow the body to soak in gasoline for about 15 minutes. the blow out all the port with compressed air and reassemble.
It doesn't take much to clog up those litte carbs.

HAS NO POWER AND DIES OUT WHEN GIVING MORE THROTTLE OR TRYING TO CUT


I have the same problem. Can't find my manual to look up trouble-shooting guide. Did following, but same symtom after:
1.) Clean air and fuel filter
2.) Replace gas lines with "tygon" tubing; check for kinks in gas lines.

Observations:
1.) Runs good for about 20 seconds then dies slow death. Starts and idles good.
2.) Air bubbles in primer squeeze bulb.
3.) Gas tank is pressurized.

My next trial and error mission:
1.) Fresh gas and oil mix.
2.) Remove gas and oil filters for bench test
3.) Replace primer tube (it is smaller than gas tube) so I cut ends and re-used old.

If you have pin-pointed the problem let me know. It sure seems like gas starvation.

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.

Troy bilt 4 cycle string trimmer wont stay running when given gas it starts fine but once you try to give it gas it dies


If this is an old unit, then the diaphragm is probably hardened.

Tests before hand would be:
1. Is the gas fresh and water free?
2. Is the spark-plug clean and snugly fastened?
3. Are you using the correct gas to oil mix ratio in your fuel?
4. yes...yes...yes...= bad diaphragm. Probably less than $5 for the part and a 1/2 hour to replace the part.

Weedeater starsts and ildes won't run or accelerate


Make sure your gas supply is fresh...not from last year...
Secondly, clean and service the air filter element... you may need to reoil it before installation...check your manual.
Disconnect the fuel line and drain it and what little is in the carb...push on the prime bulb if it's got one...
Then with a clean air filter and fresh gas... give it a start and after start, disengage the choke..
Let me know how you do..
