### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    good replacement
  

*by K***N on Reviewed in the United States on June 16, 2022*

comes with numbered jets 41 & 42. I used the 41 jet and engine runs fine with original air cleaner.  Back story-  I had over enlarged my original jet to 1/16 inch (my smallest drill bit size) which made the engine run rough at any speed over idle.

    301cc predator
  

*by J***. on Reviewed in the United States on February 20, 2020*

These work for a 301cc predator also if anybody is looking for jets for it, #41 fits mine perfect, it has and I take kit one it and it helps reduce pops out of the aftermarket exhaust.
