Non veni pacem mittere, sed gladium.
When you think about it, it's just a pump with a spark plug. Sure seems complicated.
OK, how much to change the spark plug on that?(True story- I once passed on an opportunity to buy a Mercedes Benz. Why? Because the salesman recognized that I was young, poor, and was planning to do my own maintenance- so he asked me how I'd change the sparkplugs, then opened the hood. I didn't recognize anything, it was all shrouded. I couldn't even find the sparkplugs! So I bought a Citroen ID19 instead- one of the very best cars I have ever owned, and one that I wish I still had.)
