New 2014: Intek™ Series V-Twin is rated 3.9667 out of 5 by 60.
Rated 3 out of 5 by from Good running motor but carburetor is defective. The 24 hp intek v-twin in the 2011 model craftsman mower has run well up up until this year when the carb would not get fuel. I pulled the bowl from the carb and believe the fuel shutoff valve was stuck closed. The carb is a Nikki brand that apparently has two pressed in main jets that I found to have fallen out into the bowl. I am amazed that it ran as well as it did with the jets out of place. Could the missing jets have caused damage to the engine?

Rated 5 out of 5 by from POWER POWER POWER, ALways starts Great engine. I change the oil in mine at the end of every mowing sseason (November). This engine is attached to my Craftsman riding mower. The only starting problem I have ever had was when the battery died. Never any issues with the engine. Air, fuel and oil filters are a breexe to change.The only drawback to this engine is the design of the oil drain. The valve on the bottom of the crankcase is a little problamatic. A simpler silcock design would be much better.

Rated 5 out of 5 by from Great all around power and Easy to maintain. With a Craftsman PYT 9000 lawn tractor and this engine I mow steep mountainside slopes, push several inches of snow up and down hill (w/chains), and haul hundreds of pounds of oak firewood. No oil burned yet for over two years now. Have been using a mixed synthetic blend of oil.

Rated 5 out of 5 by from So far reliable, durable, economical operation, with easy maintenance. 2005 Troybuilt 42" deck Super Bronco with the 407673 21 hp V Twin.It replaced a 20 year old 32" rear discharge Dynamark 10 hp valve in block Teccumseh & doesn't use much if any more fuel, to mow the same acreage in the mulch mode.So far no problems, starts easy, runs well, reliable, easy to maintain.I use straight 30wt Havoline, Pure One oil filter, non ethanol 87 octane fuel, the specified Briggs panel air filter, with the oiled foam prefilter, cleaned & re-oiled yearly. Oil is checked Before each mowing session & changed yearly, along with the oil filter. Fuel filter is OEM & about ready for changing after 6 years. Spark plugs are OEM & still in good condition, but are removed yearly for inspection & spark gap check.Engine runs clean & so far no oil consumption.With the exception of the oil & oil filter, its still all OEM parts!!!!I use it, but don't abuse it!!!!BTW, I also still have a Craftsman magnesium deck 18" mower with a 1956 Briggs valve in block engine, thats used for trimming. It too gets Havoline & non ethanol fuel. Still has the OEM Briggs oil bath air filter!!!!

Rated 5 out of 5 by from Intek V-Twin I have a 18.5hp Intek V-Twin in a Craftsman tractor. I believe it's 11years old now. I have had no problems with this engine, not even any carburetor issues. I use it for mowing and snow removal and I run Mobil 1 in it for easy year round starting. .

Rated 5 out of 5 by from John Deere L118 Riding Mower In 2005, I purchase a new John Deere L118 Riding Mower with a Briggs & Stratton 22 HP V-Twin engine. It was a great mower but I always had trouble with the engine starting. I replaced spark plugs, starter, etc. but nothing helped. I finely sold the L118 mower in 2011 and replaced with new John Deere L130 with a Briggs & Stratton 22 HP V-Twin engine. This engine starts instantly. Great engine.
