Cars that sit awhile.
Here's another reason not to leave 'em sitting for long periods. These are out of the original 40k mile engine from my 76 Ventura.
The car sat for 18 years before I got it, I went through it thoroughly before putting it on the road, but it doesn't get driven much and often takes a fair amount of cranking to get it started. We can no longer get ethanol free fuel here in Canada and it does evaporate. I pulled the motor out and dropped in another one that I have, got all new bearings for this one, but no hurry to get it back together, it's just a 260 cube Oldsmobile, and the other one is a 350, so I can have a little more fun with it.
