A couple of months ago I was working on my 1806 and discovered one of the engine spacers was missing. After searching all over I gave up and used flat washers in place of the missing spacer.
Jump ahead two months. I live on a gravel road with a 100' gravel downhill driveway. We have a recycle bin and a garbage bin that need to be rolled down to the road for pickup once a week each. This afternoon I walked down to the road to roll the recycle bin up the driveway and as I grabbed the handle and tilted the bin to roll it what do I spy laying in the gravel road? Yep, the missing spacer. Two months of 4 neighbors, me, the wife, the garbage truck, recycle truck, Amazon, Fedex, UPS, and USPS driving up and down that road and the spacer still lay there. Think I'll go buy a lottery ticket.
