Buy and you'll be satisfied
Style: 420cc Gas
This engine is great especially for the price point. I have it paired with a pressure washer pump 3600psi 4.8 gpm, and it has plenty of torque! Pump calls for 13 HP, I chose 16 to accommodate for name brand, and it does great. Only thing is the oil safty switch can be a hassle, I unplugged mine !

Runs great
Style: 420cc Gas
I used this engine on a bandsaw mill that I built 3 years ago. The engine gets used in the summer months to cut lumber and then sits over the winter. It starts and runs great every summer after the long (6 month) winters and all I have had to do is use fuel stabilizer in it. Plenty of power to run a 159 inch bandsaw blade cutting dry wood. ... show more

Absolutely best deal
Style: 420cc Gas
The most amazing purchase to date that Amazon has in my opinion. The reliability and durability of this machine is far superior than any other small engines I've used and it's not as expensive

So far so good
Style: 420cc Gas
Starts on first or second pull, runs very well strong engine for pressure washer 4 g.p.m pump set at 4000 psi. the 4 stars is do to the damage to the fuel tank. but it dose not effect the performance of the engine the box was trashed,but it works just fine and I would buy another one if needed.

Works great!
We bought this engine with a few concerns. Mostly being what kind of quality would we get for this price. I checked out reviews of it on other sites (sears, overstock), and it had a 4.6 star rating. So, I ordered it. It arrived quickly, and was well packed. We got it to replace the engine on our splitter, and quickly had it bolted and welded on. Off we went to test it out! Filled the gas tank, and it started on the first pull. It works awesome! The only problem we have had is one of our own making-left the choke on. Dont do that. It has made life a lot easier, and I wish I had gotten it 3 years ago! ... show more

Duromax 16 HP gas engine
I've installed this now on a shredder/ chipper replacing the OEM Briggs Stratton engine. The Duromax is a more powerful engine and can run at the low end of it's rpm range without stalling. The previous engine would tend to stall at loads that this engine just idles though----it's a good engine. It starts easily with a single pull of the rope. It's a quality made piece of machinery----compact and powerful. It is fuel efficient----with a large tank. I can't think of anything I don't like about it---and I'm hard to please. Don't know why anyone would go for the electric start version of this engine---at the increased price---when this engine starts to easily. ... show more
