The Otto-Sempto engine I tested, it is as always with Toyan engines, Toyan can make very precise CNC parts but the concept for engine development should be reconsidered.
The engines all have a shortcoming, they leak, the carburetors cannot be adjusted precisely and they get too warm.
There is considerable potential for improvement here.
The conversion kit is not needed to run the engine as a gasoline engine.
Two solenoids and the Cison double CDI are sufficient.

Awesome in every way!
I bought this engine for my 11 year old son’s Christmas present for us to assemble together & his words: “the best present I’ve ever got” sums it up perfectly! The build quality of this little engine’s unbelievable & the assembly was very straight forward with easy to follow instructions found on the EngineDIY.com website.
I highly recommend this engine & the customer service I received when asking questions prior to purchasing this engine was fantastic!

my first ever engine kit
To begin with, I'm really impressed with the quality of the parts for this engine. I enjoyed putting it together as I learnt more about engine basics. Very satisfying experience. I would say instructions needs bit more clarity but there are few YouTube videos to help. I also got the starter pack with it, had problems with glow plugs but was sent a new set. Worth the price and it's quite fun. Note to add high temperture grease to the camshaft
