I have a simple solution for your ongoing engine dilemmas.  Don't buy them.

That's not the point. If a manufacturer knows the product they designed and sold has defects, they shouldn't charge for replacement part to rectify their shortcoming.
I will buy them and if they have issues I insits on refund. There is potential in what they sell and if customers keep their expectations high they will improve.
