I received an engine from Stirlingkit and was very eager to assemble it. The instructions provided were comprehensive and made assembling the engine easy. The only concern I had with the kit is the lack of torque specs for the screws and nuts, which led to a runaway flywheel when the engine was first run. I would have liked detailed torque specs included. As for the engine itself, it was tricky to start but ran well when it finally got going. what appeared to be metal timing gears in the advertisements were actually plastic when they arrived. I would have liked metal gears, along with a better belt tensioning system for the timing belt, as the belt they provide softens and loosens under heat. Overall, I am happy with the engine kit, but wish it had a slightly higher build quality and would be willing to pay a little more. Overall it's a great kit and gave it to my son who assembled it as a fun project after finishing his first year in college.
