I tried to scan my manual for you, but I'm computer challenged. I think EdB on the other ACME board posted the parts drawing for someone else. You can also find it in the parts book or in the gas caterpillar guide. Let me know if you are still stuck and I will try to photocopy it and fax it to you.
Hicrop10,
Go to the ACME site.
Click on the "Caterpillar technical Q&A" category and scroll to the post labeled " Can anybody ID this carb off my 15" dated 8/8/07.
The parts list is scanned on that thread. The big 15 and the 10 carbs are supposed to be same except for the jets.
Good luck!
