I will be picking up a 1973 850 Spider in April - it belongs to a family friend and has been sitting in storage since ~1980. Once I get it back to the house, I'm sure I'll have a lot more questions over time.
But, my first concern is about whether it is safe to use modern unleaded gasoline in this motor? From the research I've done online, it seems that engine metallurgy from the mid-60's onward seemed to be far enough along that those engines had valves and seats from materials that could handle unleaded gas. So, maybe there isn't a worry there.
Then the next thing is dealing with the ethanol in today's gasoline. There are very few stations around me that are claimed to still have some non-ethanol gasoline available. What additives are older Fiat owners using to treat pump gas, then?
I'll post some pictures of the Spider once I get it home after Easter.
