It's an excellent running and powerful engine, especially for the price. I have 2 of them.

Like a lot of Chinese engines, they do have lapses of quality control. One of mine had a bad carb. I never could get it set to where the mid range wasn't extremely rich. Tower did replace the carb and the new carb runs fine, as does the other engine.

The one thing you want when you are buying a low price engine is a distributor who stands behind his product. Tower/Hobby Services does that. Even when I had the bad carb, and you can find other references to the same problem is you search here on RCU, I ordered the second one because I knew I'd get that one fixed and the rep for the Tower .75 is excellent.
