You guys are exaggerating...
As I mentioned..
It's a good running motor.
I tested compression with a cheapo. HF tool, and simply to confirm that I don't have a DEATH hole and I don't.
107-115 for a 74' oem engine is not bad.
Btw Battery was weak + a fairly frozen oem Ac compressor and all belts connected...
I easily add 10-15psi , when perfect testing.
And this is simply to cure with most likly new rings.
(Cast =30$ ; moly =42$)
a very easy and reasonable job .
it's a damn worn airpump ( as to expect being from 74' )and it needs upgraded sealing for better compression#
