318 has been sitting for 2 years

^^^ Starting fluid is VERY hard on the cylinder walls...... don't use it any more. Heck, we drained out all the gas that had been sitting in my son's car for just 6 months before trying to start a new engine.

Beyond 3 months, modern gasahol starts creating issues. The alcohol separates out and then absorbs water and becomes like mucilege .....
