Compression test help..

[clinebarger]

Im concerned about #1.....15% is on the high side, & air coming out the exhaust isnt good.

But not all is lost.....

Pull the schrader valve out of the "compression test whip" you were using.
Install the whip in Cyl. #1.
Connect your air hose straight to the whip.
The piston will bottem in the bore.
You will now hear the air leak out of the exhaust valve.
Using a rubber mallet, Squarely hit the top of the exhaust valve/spring.
This will "pop" the valve open & let high pressure air past....If a peice of carbon or something is stuck between the seat & valve....The air may push it out.
If the air noise stops, Repeat the leakdown test.
If you cant get the leak stopped.....Time for a valve job.
