I need help ring on Sunday
 

Hello everyone
Recently I have been getting horribly clunk/knock sound when I release the clutch. I was shore it was the gear box mount. But today I have changed it for a group n also changed the pitch mount for a group n one and after that the clunk/knock continues.
When driving if I change gear very smoothly it doesn’t make the knock and if I give it a bit of gas when near the top of the clutch pedal when releasing it doesn’t make the noise. So
Need help soon i am going to the ring on Sunday for a week and don’t want that clunk/knock noise but if i haven’t fixed it lets hope i get ther and with out problems
Any advice would be appreciated

Check the prop mount
