I enjoyed building this kit and all the correct parts were included, plus some spares. Fortunately extra red silcon O rings were included since one broke on installation (very, very tight fit on the piston). Instructions were complete and accurate.
My model operates freely when turned by hand, but I am unable to get it to run.. The LED flickers briefly when it turns but it will never run on its own. Fuel is 99% isopropyl alcohol and I've I've experimented with various wick lengths (from about a 1/4" or so to extension to just under, but not touching, the glass tube). I've also tried various preheat times (from 20 to 60 seconds} but the model refuses to run on it's own. As near as I can tell it is not even attempting to run. There is no noticeable difference between manually spinning the engine when it's cold and when it is heated.
It's very frustrating and I'd appreciated any troubleshooting guidance anyone can offer.
