05 blaster has no power at all

[lightwylin19]

I recently got an 05 blaster and it starts only after manually choking the carb with my hand. It starts to idle then dies but when I try to ride it, it won't rev up at all no matter how much gas I give it. it sounds the same at full throttle as it does barely giving it any gas. It really makes no sense because it revves up with some hesitation but it still built rpm. I'm not too familiar with 2 strokes so hopefully someone might know whats going on, any help is appreciated.

Welcome. Some things to check. Check compression, with a tester, not a finger. Disassemble the carburetor and completely clean it. I mean really clean!All jets & passages! If you use search you can find a description of the TORS system, or Throttle Override System. A sometimes problematic electronic throttle safety system. You can also find tors wiring info and how to delete the system if you choose to. Just about anything you could ask about Blasters is answered in the search archives .
Good Luck!

I cant help myself, but there's just so much nonsense out there.

First of all, the TORS system does not control fuel at the carburetor. It's a module that's tied into the engine's kill circuit (Black/White wires) that provides a means to kill the engine in case of a throttle fault...

There's a simple on/off switch at both the throttle and carb. Both switches attempt to complete a circuit between ground and the TORS module. The one at the throttle is normally open (infinite resistance) at idle while the one at the carb is normally closed. When you crack the throttle open BOTH those...
