Wow! 4 blocks is a long push with this heavy beast!!
I actually considered pushing it for a moment, but there was no shoulder, and cars were constantly whizzing by. Instead, I called a buddy who lived about 20 blocks from where I was, and he had a can with some gas and a funnel. I suppose that's cheating, but oh well. I was on my way home from work, and didn't feel like expending the effort.
I can say to the masses, when it runs out, it dies, then after restarting will run for another couple of blocks, and then she's done. Consider that first cough your only warning before parking it.
