Nice little engine
Nice building kit of a 7 cc 2 cilinder engine. The kit is very complete, and easy to build. Only one minor detail : the box with small parts and screws is not transport proof. There is space between lit and box that alows the parts to move and mingle. It becomes a puzzle. The engine is OK after the puzzle is sorted out. Nice engineering.

nice engine, fast delivery
I spent a day to put all the parts together and nothing was missing, no left overs! Nice machining. I used the conversion for gasoline and in the beginning it didn't start. I found out that the hall sensor works only one-way up, so, after turning it around, the motor started and runs very well. I suppose it has to run in, because taking over from stationary to full speed doesn't work so well. I fiddled with the mixture screw, but that did (up to now) not help much. Also it became very hot. After longer run in, i think, it will turn much better! But, all in all, nice motor, well made!

what a nice little 4 stroke engine.
I received this little engine a coupple of months ago. delivered fairly fast with DHL.
I spend a coupple of evenings putting the parts together as described in the manual (online) and the thing would not start no matter what i did. It turned out one glowplug was defective and a little complaint was filed to Engine Diy. one week later a new glowplug (os brand) turned up in my mail box at no cost. this i super service!
after running the engine wich startet rigt up after the new plug was installed, I broke a starting belt ... simply by running the starter for a wery long period due to the glow plug failure and a lack of attention to the "preload" of the startingbelt. I ordered a new one and wrote afterwards to DIY that they were welcome to send one for free due to the glowplug that lead to the startingbelt issue. a coupple of hours later i recieved a message from DIY: Dear Sir, we will send you two new belts! This is unbelievable god service and I am not sure that I would get such a service even from my local Hobbyshop. I am wery pleased with the service and the shipping time. The engine is nice and priced fair or maybe even cheap to be honest. I would like to se an engine in almost same size that woud deliver aprx. 1,2hp. and with watercooling ... if it was a 300usd. engine it would be ok with me as long as it could deliver more power and run cool (watercooling). Conclusion: super service, cheap, nicely build product, fast delivery ... whats not to like.
