Robin's timing cover colors

[Blind Old Coot]

Hi,
Is there a standard of timing belt colors for these twin cylinder Robin's engines ? So far, I've got a 2006 TXT daily driver with a grey cover that says 295 on it. Also a 2002 Workhorse with a black cover and has 352 on it. Then come home with a 2007 Refresher that has a grey cover and no label....so.....without taking the head off to measure bore and stroke...

I still see engines and parts for sale with a grey cover and has 350 on it....

The Refresher has a curtis cab and mesh doors on it for sale if anyone is interested.

Also understand that motors and parts get swapped all the time...just wondering if there's anything else I can look for.
Thanks.

grey are MCI engines and black are Pre-MCI engines displacement is marked on the block itself down where it mounts

TA DA.. I found it. It's on the back side of block towards the bottom. On the transaxle side of the block.
Thank you for clearing my misinformation.
I'm in the process of pulling the transaxle because of a few bad bearings and as I was wiping the block...I found it.
Super cool friend, I would rather know what it has for getting correct parts.

Looks like I'm glad I got into the transaxle, found one loose bearing in it. Where did they go ?

Spent a couple of hours with EZGO on the phone and online to get seals and bearings..
Something like this I prefer OEM items. . I did get cyber Monday prices... just need to wait till parts show up.
