I received the engine kit very quickly and it did come with the full color instructions it went together well However once it was fully assembled it didn’t have any compression I found that the valves didn’t have any clearance I ended up sanding about 10 thousandths off of the lash caps that corrected the issue. I purchased the gas conversion kit and the engine runs well however the “new version” CDI unit didn’t last more than a couple minutes so I can’t really say what the longevity of this little engine is on gas enginediy did stand behind the failed unit and has shipped out a new unit

Semo engine 4 stroke nitro model kit ST-NF2
I would recommend this kit to anyone who is handy with tools and has some mechanical experience. I would first print out the directions and review several YouTube video's. All the parts were there and the kit went together easily. The only trouble I had was starting the engine. Check your ground to the glow plugs. I had to move mine closer to the plugs. Engine runs good.
