if it runs fine then run it. a better tester with the right tip will give you a more accurate reading, plus with the throttle open. if the compression was bad, it would start hard.
If you have 10psi of vacuum because your slides are all the way down you will have 10 or maybe even more psi less compression. Now when you mentioned it, I'll run a test with full throttle and no throttle at all, just to see the difference. Sent from my VOG-L29 using Tapatalk
You will not get a accurate reading with “bad” reeds. Throttle open to allow Maximum amount of air into cylinder to compress. Sent from my iPhone using Tapatalk
