Style: 208cc Gas
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...

I had my doubts about this engine being such a good price point but it pleasantly surprised me! I purchased this motor for my sons go kart along with a torque converter kit and it works great. Tons of low end torque for hills but still has good top end. The electric start switch did give me a little bit of a problem but i installed a remote push to start switch that fixed that. The engine puts out plenty of charging power as well. It keeps the starting battery charged and we run 5 LED offroad lights no problem. I was worried that the motor my not be able to handle the bumps of off roading, especially since my sons go kart has the motor mounted on the moving portion of the rear swing arm/suspension, but it runs strong regardless of terrain. It has even be rolled a few times, but we flip it over and it fires right back up with a few puffs of smoke. This motor has given me the confidence to try other things from Duromax. I am look at their generators. If they are anywhere near as durable as this engine, I will be happy. And again, if you want to use this for a go kart, get the torque converter. You wont regret it.

Got this one to replace my old one without key start. This engine is great and I like the design, however, I did have some issues when starting it up. You have to put E free 87 octane or higher in or else the whole thing doesn't run and you have to take out the spark plug and reinsert. The noise level isn't that bad and it starts fine now, I do sometimes get worried that it can't handle the higher load but so far its great.

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.

Installed this on an older Ditchwitch 24" model. Basically dropped right in, got lucky and the shaft was exactly the right size, and it runs fantastic. I have yet to wire up the key start, but it starts the first time, every time. Sips gas. An excellent replacement for the worn out honda original.

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
