RE: Dynaflite Decathlon/Ryobi 31cc conversion combo?
I had the ryobi in the dynaflite fly baby and it was a perfect setup at 13 lbs. I would say go for the poulan 46cc or homelite 45cc.My poulan with magneto ign. and h9 aluminum mounts come out to 4 lbs and the ryobi is just shy of that by 8 oz so for 8 oz. go with the poulan.
