Happy customer!! I ordered a little air cooled petrol hit and miss Oddball engine. Received my order very soon end very well packed. The M96 Mini Horizontal Air-Cooled Single-Cylinder 4-Stroke Oddball Hit and Miss Gas Engine runs very good right out of the box. I’m a very happy customer!

Retrol HM-01 Hit & Miss engine. In 2023 I pre-ordered a Retrol HM-01 hit and miss engine from Enginediy which I knew would take a couple of months for delivery because it was still in pre production. I was happy to wait and I was kept informed of progress and expected delivery. It duly arrived very well packed and beautifully made. This was my first attempt at building an engine but it went together perfectly. The instructions were mainly pictorial and a little more written description would have helped but all my questions were promptly answered by their excellent service department. I have been running this engine for four months now and I’m delighted with the design and quality. I would certainly recommend Enginediy and will be using them again.

Total satisfaction. Have been in contact with the guys at enginediy regarding a shipment from them. The model engine was not only sent quickly and received within a few days, but the quality of the kit was outstanding. I didn't know what to expect with this sort of kit, but I really am not disappointed. My communication with them afterwards has always resulted in swift and very friendly replies. I would have no hesitation in dealing with them again. I definitely recommend them.

No customer service & they delete negative reviews I've made several orders from them and always got what I ordered. One expensive item (<$1K) arrived with some inexpensive parts missing. I provided them with the prod #, missing parts#, part description, & photos from their assembly manual. Many emails were exchanged. Still, the service tech was unable to correctly identify the part. He guessed at it and twice sent me the wrong parts and then gave up. When I wrote a negative review, they pulled it off their site.

They don’t respond to emails regarding… They don’t respond to emails regarding their product once they have your money. I purchased 2 engines from them and they both don’t work. Don’t waste your money here
