Picked up a line trimmer on the weekend, no brand, model etc, just a bunch of warning lables on the shaft, and a lable telling me the mix (And NOT to use No-Lead Fuel) on the tank. i was told it might be a Ryobi, and it uses a choke that i recognise as possibly ryoby, but the only specific mark i can gind is the serial: 207011973
it came with a spare engine, this engine was very similar, almoast identical, and it was branded "Piston Powered Products" Model 99A, its serial is 9085888,and the carby is missing.
I dont have pictures with me right now, but i did find this picture of the spare engine (mine is also Yellow, and the no-name trimmer is green)

Mine is detached, and has no carby/choke section, but its the same model as this, the green one is pretty much the same, and has the exact same air filter/choke & muffler.
Anyone heard of Piston Powered Products, apparently they were/are in Arizona.
If anyone can shed any light, that would be great, particualry brands, carby make & model, and age???
