Default Re: Compression test gauge fluctuating

I can't watch the video but it is normal for the reading to go up, but not bounce back. There should be a check valve of some sort in the gauge. Sounds like that it is sticking. You can probably rent a compression tester from an auto parts store. You may be able to spray some PB Blaster in there to clean it.
