Sorry for another question. What do you mean by "Jane's publication"? It is not a common phrase in MN.
Jane's is a series of books on military weapons of all sorts. It's an exhaustive resource and they cover everything you can imagine.
Here is a link if it's military Jane's has it. http://www.amazon.com/Janes-Tanks-Combat-Vehicles-Recognition/dp/0004724526 http://articles.janes.com/articles/indepth/jiw.html http://jawa.janes.com/public/jawa/index.shtml
"If you have more miles on your snow blower than your car, you live in New England." "If you can drive 75 mph through 2 feet of snow during a raging blizzard without flinching, you live in New England."

The meager snowfall in Minneapolis gave me some user time on my Honda, I did 3 driveways. Here is what I found out with that very very short time of use. I found that I need to always be around 1/4 throttle to engage the trans. Going from fwd to rev is great and is fluid. I am having a hard time relearning the right hand shoot turning handle. It seems just SO unnatural. Time will change that. With such little wet snow I have only that to go by on how this Honda is compared in performance to my Yamaha. As it sits with this snowfall I feel the Yamaha can throw snow farther, and has more torque, but it is a new tight motor, so I will have to give it time to break-in the motor. I did do some heavy load runs on a bike path next to my house. I would throw snow directly in front of the snowblower so I could put a nice load on the motor to start the proper high load piston ring break-in procedure. If we have wimpy snowfalls and I can't get a good load on the machine I will keep doing the bike path runs so I can break the motor in right. I will be doing my first oil change today. I did notice that the Honda has a very conservative governor system. After about 5 hours of break-in time I think I will turn up the rpm another 200rpms. Depending on how the governor system is designed, this may help that issue out.

It would be great if you can take a CT scan pre and post of the procedure since intra-operative MRI maybe too dangerous.

There are specific ways that are tried and true "in the real world " of engine building and are considered "best practices". Believe it or not, it gets to the common at large community and it is completely opposite of the best practices way of doing things because they think the manual is right and nothing can deviate from it. It is because people completely believe the manual and the service guy/manager as gospel. I use to build engines for or car club and was going to become an engine machinist before I went down another fork in the road when I was younger. When I was younger and before the internet, I had a 20 minute conversation on engine building and break-in procedure with Mario Andretti's chief engine builder when Mario was just after his prime. This break-in procedure is time tested and is done by all high performance engine builders to date and works right down to your lawnmower, or should I say snowblower because you would have to fill the bag and get the mower deck full of grass mulch to load that machine. Honda Marine had massive issues with badly broken in marine engines because of following the "baby a new motor" scenario. They were getting a ton of engines "making oil" because the rings did not get seated from the "baby a new motor" procedure of breaking-in. They then told those people, change your oil, go do a ton of zero to full throttle starts to load the rings to finally break the rings in right. They only do the babying way of break-in because if a motor is overly tight you could have an issue on their end for warranty on 5,000 to 30,000 units, it is an actuarial issue to them. Rod and crank bearings are broken in in about 10 to 15 minutes of running. Most of these small engines have no true bearings and use the actual material of the rod itself as the bearing, except small rodend bearings at best. Then your break-in is all about seating piston rings and the ONLY way to do that is high load. When I built my motors I would let them run for 5 minutes before taking to the streets, then after 20 minutes of driving with some light loading at low rpm I would go to this large double hill in my area. I would be in second gear and go up the hill and be at WOT and keep the rpms at 4,000 with my foot in the brakes. I would do this about 6-8 times multiple times as not to piss off the home owners and even do it on flat areas to load the rings. That is what they do on the dyno when they break-in race motors. Breaking-in a motor is all about seating the piston rings, Period! Then you go home and dump the oil. Millions of very fine metal particals from the cylinder cross hatching that are getting worn off are are smaller then 10 micron are passing through your filter at this time. The most wear on a motor is in it's first hours of life. It is not a secret, but here is one of many who know the right way to do it. Example second link. http://www.mototuneusa.com/break_in_secrets.htm http://www.helmethairblog.com/tips-and-tricks/how-to-break-in-your-engine-the-proper-way/ Another scenario are car and truck brake break-in or bedding. The common person ( and some service managers) think you have to baby brakes to brake them in. Wrong, the way to do "best practices" break-in procedure is run them for about 15 mins driving around town. Then you need to do hwy runs of 60 to 70 mph down to zero multiple times to smoke your brakes. You could have a lot of smoke coming off your brakes and the average person has to pick the right place and time to do this. ( that is why they don't tell you to do this, it could be dangerous for most people to do) You must not stop after this and let the brake pads sit at a stop sign or park your car. You must then drive to cool down your brakes to a common driving temperature. As per link. http://www.zeckhausen.com/bedding_in_brakes.htm Things are not always as they seem, and what the manufacture tells you is not always right, EVEN if it is in the manual. The right way can have safety issues and $$ issues for manufactures, so the common guy gets the wrong procedure that is cast into folklore as the right way to do it. When it is not the best way to do it. .
