What is this part

A furd friend of mine had a 289 rebuilt and it would not start after all the work and money he put in it, I drove to his shop and put some 30 wt oil in an oil can and squirted about a tea spoon full of oil in each spark plug hole :-D
Yes they thought I was wasting my time till they it the key and it spun over about two times and fired right up :-D
No compression until oil hit the rings :read2: we had a big laugh and I have told this true story a few times. :happy10:
You may what to keep this in mind when you get ready to fire it up :happy10:
