Common Carb Issues

Just trying to get a list of common carb issues for a 2002 TB.

From what I was able to get from the parts guy from the dealer was the following.

- The needle and seat was a common part to wear out which hinders the carbs ability to prevent fuel from back-flowing out and getting into the air cleaner.

- The pilot jet. Mentioned that it can be cleaned but at $6 it is not a bad idea to replace it.

I am currently trying to resolve a car issue I have right now and would love the feedback.

Please let me know of any other common carb issues. Once I get a bunch of isses I can post the issues and cause.

Hello, I just posted a carb iddle problem earlier today.
I wish I would have seen this thread, I went through all the post and I found nothing that explains my problem.
Unless its the choke problem described in the diagnose on first page. I am no mechanic, I use youtube allot.
Its a 2004 Trail Boss 330 that was not started in over a year. I changed spark plug, cleaned the gas tank, cleaned air filter, oil, new battery, and opened and cleaned the carburetor. Engine starts right up ussing the choke after I take choke off it stays rev up very high wont go down. Any suggestion, advise welcome thx allot for any help.

Thank you,
It may be the throttle cable it is very tense. Will have to check it out tomorrow after work. There is no play in it. I just need to know how to adjust it at the carburetor. Cable is free along with the choke cable. Too dark at the moment. Thank you for your help.
