I have problem with ball trough mechanism from the begin when I have the machine.3-4 years and always was thinking that the problem is from the rollover switches because the were not original and the balls go trough little bit more hard.
But these days had a chance to have brand new and more soft Chery switches compared with these that were on the machine.
So I replaced all of them but the problem still stay the same-Not every game but form let's say 10 games at 2-3 the first ball stuck somehow before it go trough to be kick from the kicker.The claw move of course but the ball stuck somehow very close to the claw.So I must open the coindoor and to roll back all the balls and at this situation the machine just end the ball.
I was thinking that may be the claw have soften spring and it moves much faster and the first ball just cannot go trough.Put much hard spring but effect was minimal.All coils are original and working.No hacks on the mechanism,everything is like should be.
No I think that the level of the machine is not so right compared with my WMS machines.

What is the normal or optimal high at the back and front?
I think and my front legs are not right too.They are much tall than the back and don't have the yellow sticker inside them.I know all SEGA have this.
Are front and back legs must have same long when they are detached ,I mean only the metal parts without the leveler?
And of course could this be the reason if the angle is too big and this thing somehow force the ball to stuck.
I made these measurement and you can see the difference.

I must find a way to see if the degrees are right.
What are the standard size of the legs in cm for SEGA?

Thank you will do it later and will report.
First will get 4 same legs 77.5.I'm sure that must have at least 4.

Yes,just feel it like I'm really on the bridge of Enterprise.Always wanted this machine to have handles.

I think I fixed it.Or at least for now.
Put the right legs and leveled it right shoud be.
And rise it from back for faster gameplay.
And the most important-replaced the through metal plate were the balls roll.Used one from TOMMY.It's 99% same just two holes on different places,no problem.
Played several games even completed master mode.For now it's good.
