ORIGINAL: Antique

This argument is so stupid it defies reason...It doesn't take a rocket scientist to make a rear carb for ANY two stroke...ANY machinist can take a few measurements and make a case...The way Rich did it is the hard way, all manually...It takes very little skill to mill off the back of a side intake case, plug what's left of the holes in the side, and make a G10 cover that fits over the hole...Get a reed assembly from any other Chinese engine, drill a few holes for the carb..I made one, worked well, gave it to TKG...He's using it on a test stand engine..
NOBODY had to make any blueprints for anything, or STEAL someone's design..A high school machine shop class could easily do it..
Rich did a helluva job with his manual machines...DLE didn't have to COPY anything, they already had the original case..They changed the mold to omit the side part and made a hole in the back for the reed...It's ELEMENTARY, not even a challenge, unless like Rich did, use manual machines...
I guess they ALL copied the DA 50...Or a Ryobi weedeater, I had a Ryobi 28cc made EXACTLY the same, at least 20 years ago...It had rail mounts and a mag ignition (They must have copied Zenoah, the coil looks the same) It came with a header and long cast motor mount....It was sold by Hobby Lobby as a combination with an airplane..There was one at the old QSAA in Vegas WAAAY back there....
Get over it guys, there's nothing new under the sun....Unless someone copies our not yet finished 80cc racing opposed twin with TWO rotary valves, one front, one rear, COMPLETELY made in Flagstaff, Arizona, USA..Pistons, cylinders, crank, rods, crankcase, etc..ALL made on CNC machines with F@#$% near perfect tolerances by a hot rod record holding legendary machinist..
I could tell ya but you know the rest [>:]
