Air compressors in adverse environments don't hold up that well either, without basic maintenance. I've had engines run seasonally for decades. It doesn't take much for them to keep working well, though doing nothing at all is an easy way to clog up the carburator.

You have to empty the compressor of wate. Some times a lot of water. I've seen a 33g tank with 25gs of water.

Compressor pistons/screws that ingest grit/dirt, or aren’t run often enough to boil the water out of them, also tend to not last long. I used to help run a volunteer workshop with an Atlas Copco screw compressor, and it died in a few years because it wasn’t being run hard enough and the screws rusted (doh!).

It shouldn't be that bad. A little fogging oil when put away and drain all the fuel. Then a little starting fluid on the first couple start attempts. Usually they start fairly quickly if they're in decent shape. And that's just for pull starts. My electric start mower starts right up after even 5 months of not running with stabilizer in the fuel.

God bless Lucas stablier, and damn Joseph Lucas, prince of darkness. Any chance the stuff in Spain is made in England?
