Walk Behind Lawn Mowers

I bought a Husqvarna 775EX last year about midway through summer and only used it for about two months. First time using it this year and it won't start. I had already replaced air filter and spark plug, changed oil, and put in fresh gas. Took mower apart, made sure fuel line was good and carb was clean then put back together. Mower starts and runs for three seconds then shuts off. Out of ideas, I called customer service and based on everything I told them they figured that the mower needs a carb adjustment. I can not believe that this is not covered under warranty. Only two months of use and I am already paying to fix this and the nearest service center is over an hour away. So add in the cost of gas to the service center and in less than a year I am already going to be paying over a hundred dollars to get my mower to run. Last Husqvarna I will ever buy and will not recommend to friends or family. Terribly disappointed in a product I had heard good reviews on. As an active duty member of the military, had this happened to my wife while I was deployed I would be dropping this mower off at the company headquarters.

I have a brand new Husqvarna walk behind real wheel drive self propelled lawn mower model HU800HW. I just bought it last week and it works quite well overall but a couple of questions:

1. The gears for the wheels made a grinding sound on the left side. I took it apart and can see the large gear (inside the wheel) and the smaller gear (connected to the drive unit) were not quite meshing together properly when the wheel spins (these 2 gears always stay locked together normally). I swapped the left and right wheels and the noise went away for the most part. The dealer I bought it from said there are different part numbers for the left and right wheels and maybe the wrong wheel was put on the left side. Is that possible?

2. The gears in question 1 above do not have ANY grease on them. They are totally dry. Should they have grease? And if so, what kind? The dealer I bought them from thought they should have some grease on them and recommended regular automotive grease although some people in forum online said I should use high temperature/pressure lithium grease. What do you recommend for these gears?

3. The mower drive wheels lock up when trying to pull the mower backwards more than a couple of feet. Is this a feature to prevent it from rolling back onto the person mowing? It makes it very difficult to mow since half the time with a push mower (even self-propelled) you have to pull it backwards to maneuver it around objects. This could be a deal breaker for this mower - I'd really hate to return it. Maybe tell the R&D folks to fix this in next year's model if it can't be disabled. Is there a way to disable this feature?

4. This is more of a comment - the side discharge chute that I had to wait to receive in the mail should either come with the mower or at least be available at the place of purchase (dealer) optionally. Many people complained about this on the forums - if you don't want to bag or mulch (which doesn't work with taller grass) - you can't use the mower until you get the side discharge chute. It would be better if you didn't make folks who bought the mower have to wait for that part if they know that is how they are going to be using the mower.

I have a Husqvarna HU800AWD mower with a Honda GCV190 engine. I've ben told this mower MUST use:
92 octane gas with NO ETHANOL
5W-30 full synthetic motor oil
NKG 509 spark plug
I must ad 1 or 2 fuel filter in the fuel line
Must use a high capacity air filter with a pre filter in front and back of the air filter
Is any of this necessary?

I have a Husqvarna lawn Mover (walk behind, serial number 110909M000607) That is brand new (only used 3 times). It will not run unless the choke is wedged open all the way. Please provide assistance.

Also, this mower did not have an air filter in it (just noticed that today). Should it and if so, what is the model number and type I should get.

Thank you.
