RE: Bisson Muffler Mfgr defect?????
We are doing performance evaluations on our new ZDZNG 50 -using the Bisson Pitts (same one fits on the DA50.)
So far so good - power level is extremely good
As far as we can see, as good as any 50 size motor now .
The muffler is staying on with no lock tite - and so far no loosening -
so fa so good --
