Yes, Tanaka makes great 2-stroke engines and you pretty much get what you pay for at that expense. They burn very clean running 50:1 as recommended.
A little note on the 47R race engine they produced.....everyone that I owned eventually ended up with a broken exhaust flange which rendered the engine useless. Be very careful how you mount an exhaust (other than the stock can) to it or vibration will crack the flange.
I think I broke only one flange on a PF4000 of several owned.
