There are alot of good guys on this page!! George is the reason my series one is still running.
My rods don't have any holes in them. I cannot confirm if they are original though. It was put together with series 1 and 2 parts when I got it. (Series 2 block and series 1 crank and rods). It's has a series 1 block now.
I wouldn't put any more money than what's needed to make it run. On that note mines been working pretty hard since it's been back together. Took care of snow all winter(the most snow we've had in recent years!) and now lawn duty. I run 20-50 oil with extra zinc all year (garage is heated in winter and I make sure the oil is hot before doing work). due to my dads recomondation and has been working for me I guess. Just buying time to get a replacement at some point.
