For a cheaper engine, this has amazing power, and is very easy to tune.

Pretty solid engine for the price. Tuning is a bit tricky but once it’s tuned good it’s got plenty of power (especially bottom end). Really good throttle response even when rich. Only thing I gotta say is that the pinch is really tight. Like really really tight. I probably preheat the thing to 230°-240°F before I can start it (the starter box I use is quite old and worn so that’s also a factor). Something that is very very good about this engine is the fuel mileage. I was getting around 11 minutes on one tank still tuned on the rich side. Definitely worth the money. Just open it up before you start it and make sure everything is ok.

This motor is absolute garbage. I know it's broken in--no catch at TDC with plug out when warmed up. I've tried 3 pipes. It makes NO power, like it's just broken. There is no tuning it to do anything other than be an absolute dog that takes a year to wind up. Actually left an event because I couldn't even get over the jumps. Disassembled, looks fine, no indication as to what is wrong. Starting to think it came with mismatched internals or something. There's no instructions that actually tell you what the head shim options are, no resources online, and the engine isn't even listed on their site anymore. Best $170 paper weight I've ever bought. I've had OS, werks, reedy, nova, and ran nitro for over 20 years. Absolute worst motor experience I've ever had. IF there's anything that will make you spend the money for a speed motor, this one is it--so much time down the drain trying to get "meet all your needs" to do anything than run like a dog.

Shipping Package showed up in perfect condition plastic box inside with engine in it smashed, only way this happened is it was damaged before packaging and shipping out. Guess we'll find out if crank is bent. Not happy but oh well.
