Bill Cunningham and his fine folks overhauled an IO-550 and it has run perfectly for the last 4 years. He asked what I wanted, made suggestions, and built a fine engine. When I called he answered the phone. He did what he said he would and fulfilled his promises. I have no reservations about recommending his company

Thx Bill, great owner to work.

Great guys and good initial convo about aircraft engines.

DO NOT USE THIS COMPANY, ZERO SUPPORT, VERY RUDE OVER THE PHONE, TAKE YOUR BUSINESS SOMEWHERE ELSE THAT PUTS CUSTOMER FIRST. YOUVE BEEN WARNED
