You should also check the weight and balance information for the aircraft. The 2200 engine is very light and I have heard of an instance of a 2200 Sonex having dangerously aft C of G. It probably should be polished rather than painted although a friend has a beautiful painted 2200 Sonex. He used a prop extension to help get weight a little further forward.

A 80 hp Jab engine is an excellent choice for a Sonex A model. Like most things we do in aviation its all about compromises. I fitted the extended prop hub not only for CofG reasons, it also allowed me to use the Jabiru supplied ram air ducts and it also allowed me to fit the oil cooler at the front of the engine. There is a fair amount of work in modifying the cowling to push it forward the required amount.
Hope this helps
