I had my engine over hauled to the tune of about 20 grand. Its suppose to go 2000 hrs. They put in used parts and logged that they used new. 200 hrs in I need another overhaul. Compressions below 20 on 2 cyl. At annual. That's when we found out used parts were installed. They won't even return my calls now.try them at your own peril. I would give zero stars if was a choice.
