Heres a pic of my 61cc echo twin and you can see how the reeds are setup.
Notice the intake manifold is facing,thats how it bolts onto the case and it matches the BME shape of the case.The bolt pattern is exact also.
The only way for the parts that you ordered for the style that was posted on this thread is to make a new adaptor that your parts will fit to.We have the older case.This could be made from aluminum if your block from the homelite is G10 or similier.It would have to be thick enough so the pyrimid doesnt hit the journals on crank.
I am going to call [dandb] and see if they will sell me a set for the 61cc.If its the same pattern.
The other thing to do wich i might is to use 2 petals from the 33 saws as pictured above and screw them to a homemade block.In other words make my own 2 petal desighn reed block.
I do have a reed block coming from a stihl 33cc wich will work easy but i dont know if its big enough.Or ill just use a bigger carb.Ill post a pic when it arrives.

GaaauuullDarnnnnnit.Forgot the pic again.First the gray[silver]hair and now this.Crap!
