  1. John Wilson

    I purchased this UMS 5-75cc from Adrian last June as soon as stock became available. It has been an outstanding investment. Very reliable and very easy to start. It has been a great deal of fun. So pleased with the purchase, I recently bought a UMS 5-125cc. Adrian provides fabulous support and super fast shipment. Adrian has gained my loyalty and the one stop, sole dealer for me whenever I need a multi-cylinder radial. I can not speak highly enough about CH-Ignitions and Adrian. There simply aren’t enough “stars” available to give a truly righteous rating for the appreciation I have for this business. As a matter of fact, I also purchased an EME70 from Adrian. Six months later, out of the blue, I received an email inquiry from Adrian asking the status of my engines and whether everything was okay with them. It doesn’t get any better then that!
