Gonna do a complete writeup and review with pictures really soon. Just now working out the bugs and finally getting it to run now but only on the glow plugs and homemade fuel so far. Could not get CDI and gas to work properly yet, but carb wasn't set correctly. Had no idea where to even start with the carb, not that I don't know how to tune a carb (first time tuning this size and kind of engine though), not even that I didn't eventually find some help online (from Stirlingkit more though), or even after all that I could even understand the very very very hard to understand directly translated instructions in fact it would have all been easy except one main thing:
The damn instructions assume you have experience with this style of carb and know which needle is which, and it does not label what is the "main oil needle" or whatever anywhere and if you don't know then your lost. It took taking it apart for me to even realize oh duh it's just a slide carb, with diaphragm pump.
If the instructions labeled the needles on the carb and maybe even have the user themselves assemble it, not have it preassembled so they have a better understanding of how it works, it may make it easier for beginners to get it running.
Cause I'm sorry folks, unless you have worked with RC or model engines before, no these engines are not easy to get running like advertised. They do not just start right up like on YouTube.
But don't get me wrong it's been fun! I'm just the DIY/tinkering/tweaking/inventor/pioneer/too smart for own good/just plain bored type. Peace
My advice so far is start with what the book says and use nitro fuel and glow plugs and run it as a compression type engine first until you verify it's good, and get the carb tuned for that first. It will make it easier to tune it to gas, and make sure you use either your own or a good (old version) CDI. Personally I plan on scraping the hall sensor and using something like a photoeye maybe.
But hey what do I know about engines my degree is electronics engineering. But I'm trying. Also in the future will be doing all kinds of would like to do all kinds of reviews on different mods, as well as using different DIY or commercial fuels. Hydrogen would be cool. I can see hooking on up to my HHO torch machine and running it off of that using water as the fuel. But also maybe something homemade and free like woodgas would be awesome also. Look forward to my reviews on the future but be patient. Also will be doing an enjomor L4 with turbos and Toyan V8 new version, flat 4, etc.
**Btw the picture isn't it's current state, that was when I first built it straight out of the box. I had several problems some of which or most/all of which seem to be common with a lot of people and it takes so long for EngineDIY or Stirlingkit to process and ship stuff, so I had to kinda build my own quick makeshift electrically insulated base to mount engine upon, which mounts to semto base, as people know the screws don't line up on the semto base properly!!!!! However, gonna do the detailed review on the Toyan X-Power-A water cooled version I bought from Mechartisans off of SHOP app. It came like ten times faster than EngineDIY or Stirlingkit, and was cheaper, came with starter/water kit etc. more on this later**
