029 56.5cc yes I have done one the power is great but it is about 3/4 lb. heavier than the older 56.5cc the 031 and 032, you need to make a beam mount just like the poulan 42cc it is put together the same way and a carb mount that I can make for you if you like.the total weight after making a prop adapter carb mount and beam mount brackets will be a little over 4 lbs where the 031 and 032 will be just under 3 lbs so if you dont mind the weight then it would make a great power plant.it is also a drop in engine so no triming of the case is needed.I can make any parts for this engine you like just email me.
