I’m having trouble getting my lower cannons to work. They function but they don’t hit the ball hard enough to push it to the top. I have had them apart and cleaned. Is there anyone here who can rebuild them? Here’s a pic of one apart. I have a video of function but can’t post it. Any help would be great.
