This is driving me nuts!
I took the idol off, the yellow plastic and the motor below to clean them all.
Now when I put the idol back onand tighten the set screw to the flat part of the motor post, the idol seems to sit too low - so balls can't enter it (see photo). If I lift the idol up to make room for the ball, it will no longer tighten onto the motor post as the set screw is now too high.
I thought maybe the motor post is sitting too low, but it looks the same as a 'before photo' I took - about half an inch above the yellow plastic - and I don't think there's any way to make it higher anyway as the motor below the playfield is screwed in properly.
I'm sure there's an obvious solution but I've been working on this for an hour and it's killing me!
Please help somebody!!

No, pretty sure there was nothing like that. It definitely fells like I've missed something though

Haha - thanks for the suggestions. I'll take another look tonight and probably take the whole bugger apart again (the only danger is my wife who gives me stink eye every time I disappear into the pinball room - no poison arrows though at least)

Worked it out - schoolboy error. I had reattached the 3 way metal bracket to the idol the wrong way up - so that the central bit was sitting into the idol, not out of it. Kind of obvious now, I should have examined the diagram in the manual closer...
Thanks for help anyway guys. Almost dialled my Indy in finally now, all LEDded up, modded up (bi-plane propeller, lost plastic with lights, jackpot lights) and cleaned and waxed.
