Re: 1994 Fling Turbojet Compression Check
It depends on the condition of the piston rings and cylinders and your elevation. The important thing is that the compression be within a tight range for all 4 cylinders.
If you took the readings with a warm engine and the engine had new rings, I would expect about 125 +/-at sea level. Just put new rings in one just like yours three weeks ago and that was the result.
Before that we had around 105 in 1, 3 and 4 and 80 in number 2.
