Rated 5 out of 5 by from Good value engine I too received the chinese made, cheapest B&S engine available with the aluminum cylinder and plain bearings in my Poulan Pro roto-tiller. I wish B&S would not hide these attributes in their engine serial number so that customers know what they are getting. Had I known that I would have gone with another brand that offers the no-name Chinese engines that have a cast iron cylinder liner and ball bearing supported crank standard.That said, not all is lost. This engine has more than enough grunt and powers my roto-tiller reliably. Starts on first pull every time, and runs smooth and relatively quiet. Controls and engine exterior have a look and feel of quality to it. I'm sure despite the cheap engine internals (where it matters most) I will still get a lot of years use out of this engine, and the tiller it's hooked to. After all, it only gets used for about 10 hours in the springtime and gets put away for the rest of the year.

Rated 1 out of 5 by from china motor is junk!!!! I bought my first briggs product at 10 and began making money with it. Reliability was always number 1 throughout the years as I have owned numerous briggs powered pieces of equipment. THEN CAME THE 900DRT HUSQVARNA!!!!! WHAT A PIECE OF JUNK!!! However, worst of all is the china briggs motor. From the beginning it required the muscles of a weight lifter just to crank it. VERY POOR STARTING! After replacing the carburetor it cranks somewhat better. Still it runs roughly and sometimes shuts down under normal 2" deep weeding use. Simply call me "VERY FRUSTRATED IN ALABAMA"

Rated 2 out of 5 by from poor quality and design this enginie was on a DR roto tiller. after one month the enginie seized. the instructions on filling oil are to fill till it runs over. no dip stick. you cant remove the spark plug withou taking off the muffler at least. how can they design an enginie like this? i returned the unit to DR for a refund. in the past i have been happy with B&S engines but the 900 is a disaster.

Rated 2 out of 5 by from I bought a Husvarna FT900 rototiller that was advertised as MADE IN USA only to find out that this engine is made in CHINA....... how decietfull..... I bought this machine because it had a B/S engine..I did not want a Cub Cadet or MTD or Troybilt. Its common knowledge their rngines are Chinese. I ve worn out many B/S engines in my life time and have always been satisfied with their peformance. I spent the money to buy what I thought was quality only to be deceived. SHAME on you B/S all yor advertising and Co history talk about MADE IN USA. I AM VERY DISSAPOINTED. We ll see how it holds up.

Rated 5 out of 5 by from Engine History Model 120000 Intek 900 series 12S452-0049-F8.I bought this engine to replace a Model 133452-0049-03 engine that powers a stow cm-4, which is a 4cu/ft concrete mixer. These engines are factory set-up with a 6-1 gear reduction drive. I did not like the fact that B+S did not any longer carry a replacement carb for the old engine. The engine still has plenty of life left, just carb problems. I will cover this new engine history in detail. I bougbt the engine 2 weeks ago (shipped from a midwest company to my Bronx NY based co).and mounted it on an engine stand in my shop for the initial break-in period. No shipping damaged was evident. After dilligently wiping down the entire engine and attaching the B+S maintenance minder, filling it with Valvoline 5w-30 full synthetic engine oil and Valvoline 80w-90, which is a synthetic blend, for the gear reduction drive. I than filled the fuel tank with Gulf 92 octane gas to which B+S Advanced Formula Fuel Treatment and Stabilizer had been added. Not knowing exactly what to expect, I opened the fuel valve, set the choke, slid the throttle lever about half way across and gave one pull. Engine immediately started. I know, surprised the h.. out of me too, or should I say amazed me also. Will keep you posted.

Rated 2 out of 5 by from Unreliable I have had the engine 2 years on a lawn vacuum. It sometimes just will not start come back the next day and starts right up. It is the most unreliable engine I have ever had.

Rated 5 out of 5 by from Minibike powerhouse used this engine as a power plant for my minibike and after one summer of running it is still running great. im in the process of upgrading the engine as it has many aftermarket parts available (same as the briggs animal lo206). will recommend again I love this bike and the engine stock is crazy powerfull. 7 hp stock with prem gas will be pushing close to 10 when im done. new connecting rod flywheel cam valve springs carb etc... great little engine.
