does anyone know what comp should be for an 85ESL73M? right bank is 110 both cylinders. left bank is 105 both cylinders. sound like a good motor? has been sitting and probably needs a de-carb to bring up the comp numbers. any takers?
When new, the compression was probably in the 125 range. Your engine should still run with those numbers. Not unusual for compression to vary up to 5 lbs between heads, due to the way they were originally bored at the factory-so that's normal. Agree, a decarb may help the compression.
