Here is mine in action. Timing it by the YouTube timer at the bottom it looks like 15 seconds. This is with new Chinesium rams, lubricated pivot points, and a cleaned and rebuilt motor. The ground is very important so maybe clean and re-secure that. I also had ATF leaking into my motor housing so cleaning was mandatory. When I was searching for a new motor I noticed that they all looked pretty much the same. At 3-400 dollars I decided to just take mine apart and clean it. There is a tiny O-ring seal that separates the oil reservoir from the motor and that was the culprit. I feel mine is noisier than it should be. 1968 Convertible top
