I got the XP7HP version. It's a good little engine. The recoil starter bolts are metal, not plastic, which I like. The engine is extremely loud, the silencer may as well not even be there. The only quality issue I found was odd wear on the crankshaft counterweight. Keep in mind I have not run the engine yet when this photo was taken, it was brand new out of the box. That wear is from the factory. But the engine still works, so I'm not going to complain about it on a $200 engine. The rocker arms were oiled, and looked good. After I reassembled it it started on the third pull. Then after that it has always started on the first pull. It's no high performance engine, but it gets the job done.

Style: 208cc Gas Electric Start
I bought one of these engines for a mini bike I was building. I had to make the frame anyway so fit wasn't an issue. the build quality is good and it starts easily and runs great ... not too loud. Electric start works ok but It doesn't seem to charge the battery so I rarely use the electric start...

Started up right away and runs strong. No complaints. A lot of engine for the price! Purchase to independently power a formerly tractor PTO snowblower.

Update on original review below. I've put some more time on this engine now and it continues to have a lot of power and the noise has subsided. The oil has stayed clean and doesn't have any visible metal shavings in it, so whatever made the noise must have been small. I did get in contact with the company and they assured me the warranty was 1 year, so they were helpful although a little hard to get a hold of. The tech did call to help diagnose but I've looked at everything there was to look at on this engine and never did see anything. I upped my rating accordingly. I don't know whether to recommend this engine to others or not. It arrived quickly and undamaged. The price is right. I installed it on a Troy Bilt Tomahawk shredder to replace the original under powered 5hp Tecumseh. This engine definitely makes the shredder more useful than it was originally with the too small engine. Engine runs great but sounds terrible. It had a very loud hammering noise when I first started it like a bolt was loose inside the crankcase. This intermittent noise subsided but was followed with a constant lighter hammering. It was full of the recommended oil. I used the machine for about an hour and checked the dipstick for metal shavings. Drained the oil and replaced with new. Nothing out of the ordinary was in the oil for a new engine. It does not smoke and runs like a top. I contacted the company by email and included a video for the sound and have had no response as to if this is normal for these engines. I have worked on engines small and large for 20 years and don't think this one is quite right. The noise is definitely from the crankcase area and not intake or exhaust noise. I believe it would be quiet otherwise. I thought it was going to come apart in the first 15 min but so far it has not. This is my third Honda clone engine and I had very good luck with the other two that I bought at Harbor Freight. I will report back when I have further information.

I purchased this engine as a replacement for a Briggs 12 hp V-twin. The $329 price tag was the deciding factor - that's about half the cost of the Briggs short block. The engine is mounted on a BCS 30" roto tiller. All of the mounting was ready-to-go right out of the box. The clutch slid on the keyed shaft, and the retaining bolt turned right into the 3/8 - 24 tapped hole. It was only about an hour from opening the box until I was ready to go. After reading the other reviews, I was concerned about the starter connections, and also about building a battery box. Neither was an issue, as the engine is very easy to start and I haven't felt any need to use the electric starter or connect a battery. A brief examination, however, makes it clear that the only connection necessary is the battery cables - shouldn't be a problem. My tiller has a "dead man" switch that kills the engine if the machine gets away for some reason. Using the schematic, I was easily able to figure out how to connect the kill switch. The only difficulty I encountered is that I wasn't able to connect the throttle cable from the tiller control handlebar. That hasn't been a big problem - I merely set the engine rpm before I start work, and it goes fine. The engine is a piece of cake to start - it has started on the first pull every time. It does require a fairly stout tug on the cord, usually a "two handed" tug. It seems louder than the Briggs, but I don't have any way to measure decibels, and if louder, it's by just a little. It runs very smoothly, with no surging or "hunting", and fuel consumption seems reasonable - but, without a meter to count hours of operation, my opinion of fuel consumption is quite subjective. Without a dynomometer, there isn't a way for me to measure actual horsepower output, but there is no doubt is has a bit more zip than the old Briggs. As of this writing, I have used the engine for about 20 hours without any problem whatsoever. My own measure of engines like this one includes longevity, so I might be back to edit this if the engine doesn't give me a few years of good service. At this point, I don't hesitate to recommend it.

If it helps anyone, this motor doesn't include a charging coil. After researching online, I thought it did, but my actual motor has no coil. Not sure if the flywheel has the required magnets to install one? The motor is great, but wanted to add context to the reviews for anyone wondering if this motor would support a low power headlight.
