    Mower not started in 7 years! Full tank of fuel and crankcase is full of oil. Tips?

    Hey guys,

    I just purchased an essentially brand new Lawnboy 22271 commercial mower with the Honda GSV 190 engine.
    The prior owner bought the mower brand new approximately 7 years ago, and only used it for a few hours on his acreage before storing it.
    The unit does not have a scratch on it, literally like a time capsule, so I believe him on the hours of usage.

    The only issue is, he didn't drain the fuel when he put it away 7 years ago!
    We drained the gas into his fire pit, and it had turned completely yellow like lemonade.
    I tried turning the engine over with the spark plug disconnected to make sure it wasn't seized, and it is silky smooth, no binding.

    My question is, what should I do to this mower before starting it?
    The oil, air filter and spark plug look unused, as expected for a unit that only ran for a couple of hours since leaving the factory.

    Can I just add fresh fuel, change the oil and go?
    Do I need to clean the carb?
    Any way to flush any fuel remaining in the lines or carb?

    Any advice would be greatly appreciated.

    I would change the oil, check the spark plug add fresh gas with a bit of SeaFoam in it and give it a start. See if/how it runs before doing anything else to it. Might lube the control cables if you feel any binding in them.

If you do have starting issues, I would first suspect the carb. and, would change any fuel lines that have hardened . ..

    Nice score !!

    Definitely oil change, I would add a teaspoon of oil down the spark plug hole & rotate the engine.

    Seafoam I agree for the New Gas (100% real gas) would be best.

    As other have said, clean, flush, fill with fresh oil and gasoline.

    Don't struggle to much if you can't get it started; after sitting that long, the carburetor is likely filled with goo. The good news is a genuine Honda replacement carb is usually < $20. If you'll get me the full serial number off the ENGINE block (It is in the form of GXXXX-1234567) I can get you the part number. You can then google it to find a dealer selling online.
