Anyone have an Actron compression tester.
If so, any issues using the 12 mm adaptor in the head?
TIA

Went ahead and got one.
Works great and has several size adaptors.

Rerun a wet test , just to see what the change is . I wouldnt be ashamed of those numbers.

Re-ran hot dry and hot wet tests, this time with air filter off:
141, 149..dry
150, 150..wet
But I'm wondering now if I had the tester snugged up enough on the 141 reading!
Time for another test.

Bill Silver says, 160 to 175, but that's right out of the box.
