It's kind of heavy and may not balance the plane that well
What is the weight of your 4-stroke?
I was about to put Poulan 25cc in my Wilga, but what I found that this engine that weights 48oz (with magneto) hardly balances the plane. Harbor Freight has Yard Machines trimmer with Ryobi 26cc 4-stroke. I believe it wil have performance close to my Poulan 25cc, but should weight more (and sound better). Any input?
