What an amazing little engine. I bought an m12, however it was faulty. I sent it back and enginediy sent me a m16, with a little camshaft tuning and proper engine knowledge, the engine runs FANTASTIC! I have never had such a reliable running engine before. With enginediy’s tremendous customer service, they got me an amazing running model. Starts up every single time, I’ve put around 13-15 hours of run time on it, and a lot of fuel through it, I’ve fully disassembled it twice, it’s a solid runner. If you are somewhat mechanically inclined, this is the ENGINE FOR YOU!
(Ps, I tried painting engine white, I did not prepare pint well enough, however removal was easy. Now back to normal.)
