Mr. Cox: Thanks for your reply. A throttle is defined as "a device that restricts flow to reduce power and speed." This is exactly what the Cox throttle does and why it is called a throttle and NOT a carburetor. We discussed this in detail three years ago. It is not false advertising and your comment is not appreciated. The function of the Cox throttle has been explained in great detail repeatedly so anyone considering its purchase knows exactly what they will be getting.
To redesign the standard Cox reed engines to have a carburetor and function similar to the Queen Bee would be far too expensive, well exceeding the cost of the engine itself. We also discussed this in detail three years ago.
Regarding the various homemade devices on You Tube, yes they regulate engine speed and are fine for an individual to experiment with for their own use but they are not conducive to high volume production. Please understand the requirement in designing the throttle was to make something inexpensive, easily converted, easily mass produced and extremely simple to use. This is what we did.
Best Regards....
