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.

I have a 2003 Magnum 330 that will not take the gas if the air filter is disconnected. Is this normal? It doesn't run well at all until the air box top is back on. Then it still seems to be a little sluggish but will run. I don't plan on running it with the air box off but would like to know if there is a problem lurking before I get back in the woods with it. I looked through and cleaned the carb but it didn't look dirty to start with. Problem I started with turned out to be tank stopped up at the petcock. I guess what I want to know is does this type of carb require the restriction of the air filter and box?

That is good to hear. Thought I had something to worry about. Been thinking about getting a aftermarket filter for it but if it is that touchy I think I will stay stock.
