Hi Darin,

In a previous Poulan thread you said: "I found mine a little sweet spot that was very dificult to find with the needles but I put a velocity stack on it and it is all perfect now no burble at any rpm just as smooth as a glow engine." I assume this photo shows the velocity stack you are referring to?

Is this something you buy or make? If you bought it, where? If you made it, would you be willing to share some details? Materials, how you constructed it, dimensions, etc.

Thanks!!!

Gene
