So much for the watering idea, huh? You can use a hand spray can full of light oil if you have to, but watch out for getting too much on the coal. I know first hand about the auger issues that will 'cake', and believe me, you were lucky too.
I can't say enough about having spares on hand. Motor, auger, shear pins, coupling for the blower, a spare circ or zone valve head, some control parts, wire, wire nuts...bolts.....I live out in the country, and there aren't any hardware stores close to me.and as excellent as Grainger and McMaster are, on Sat at midnight when it's 12 below and the wind is blowing 25 mph, that feeling of "I'm screwed", leaves you feeling ill.......................unless PPPPPPP! Or if you can't play 'think quick', then better go back to the porch with the little yappie dawgs, and let the big dawgs do their thing..
