Default Onan 4000 need new carb & repair manual

I have an RV with an ONAN 4000, model #4KYFA26100K and they tell me the carb ( 146-0785 ) is all gummed up. The mobile RV guy says $800 to R@R.

Two questions:
Is there a good video or instructions on how to remove the carb. Took the air filter out and see two bolts but can't figure out how to remove the aluminum T-pee looking bracket that holds the air filter in which is blocking access to the bolts.

Second, is there a good place to buy the carb without paying an arm and a leg. Can't understand why they don't make rebuild kits or rebuilds or why they gum up more than a regular car engine carb. I'm told this is a common problem so you need to run them monthly.....
