SOURCE: Troy-Bilt Chipper Shredder won't start

It takes good gas, good spark, and good air for a gasoline engine to run well. The next thing I would do is put a new air filter in it.

SOURCE: Troy Bilt Trimmer 75SS stalls at full throttle. new gas

Hello. Let me assist you. Since your trimmer runs but stalls at ful throttle it is telling you that there is a fuel problem. Not enough gas is getting through the carbeurator to satisfy the engines needs on full throttle. Most likely the carbeurator is gummed up. A common problem. Let's see if we can un gum it by getting a can or carbeurtor cleaner. Go to any auto parts store and talk to the clerk about your need.

I have an older Troy-Bilt tiller (model & serial # unknown) that when I start it (manual pull) it runs for a second and then shuts off. I checked the spark plug, fuel line and inline filter, fuel, oil...


could be bad coil. does it stay running with choke on? or half on, if so its a gas problem. could be the main jet is plugged in the carb. Or water in the carb bowl. Remove the bowl nut and let some gas run out the put it back in and try it. just guessing as not much info to go on.

I can't get it started and I"m following directions on side of machine.


Those direction are not accurate all the time, I usually prime mine 4-6 times. put mine on full choke with the trigger pressed and pull 1 time any more will usually flood it, If you have the choke that kicks off after you press the trigger, put the choke back on to half and pull the cord pressing the trigger, Then pull the cord until it starts without pressing the trigger. As before if you press and hold the trigger during the start it will flood these trimmers..This should start the trimmer. You may have to let the trimmer set for about 15 min if it was flooded.

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 ****!

Troy bilt rototiller stalls when opening choke


The carburetor will need to be cleaned very good. New needle valve maybe float and new gaskets That should take care of the problem.
