Question about Troy Bilt Tb425cs 26cc 4 - Cycle Curved - Shaft Gas Trimmer with Ez - Start and Speed Spool

1 Answer

I have a TB425cs that won't accelerate. It will

I have a TB425cs that won't accelerate. It will idle just fine and starts easy as can be but if I hit the trigger it dies. It seems to run better with the winter switch closed, but still won't spin fast enough to cut. I have replaced the spark plug, checked the cutting head for binding, cleaned the carbuerator, and removed the muffler to see if it was clogged. Also, I replaced the fuel lines and made sure there weren't any holes in the primer bubble. Any ideas about the cause of this would be greatly appreciated.

I've got a 1996 jeep grand Cherokee with the 5.2 v8 fuel injected Holley throttle body. My problem is while driving at soft or low acceleration it accelerates fine, but if you hit the throttle hard it


I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.

Hi Anonymous, if you have a carburator the usual suspects are:
1. Damaged or restricted fuel tank venting system (gas cap).

4. Accelerator pump leaking or no output.
5. Plugged bowl vent.
6. Fuel level (float chamber) too low.
7. Restriccted fuel supply passages.
8. Plugged jets or passages.
9. Worn or damaged needle or needle jet.

Good luck
