I've got a 91 RX7. After getting it I learned about the problem caused by starting and shutting off before it is warmed up. This summer I let it sit a couple of months in the driveway and now have the same problem. It spins easily and doesn't sound like there is any compression. I was told before by a mechanic that there is a way to squirt or spray some oil thru the spark plug holes to get compression started. Is this all that hard? How much oil should be put into the chamber? Would something like STP or Motor Honey help?
