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!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 little engine

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.
The idea behind our business is to make science and educational model engines available to anybody with passion of Engine DIY.
