Trying to work out the dimensions of a two stage tuned expansion pipe for my husqvana 346xp
none of the two stroke pipe design software ive looked at is suitable for smaller engines.
not a clue where to start from to do it manualy my maths and physics is no where near good enough.
any pointers gratefully recieved
anyone allready made one that works well that would be willing to share how they worked out for a correct back preasure optimum for power of saw.
