          Not at all. Remove tank... Remove carb... Remove carb bowl... Oring is visible

                Very hard to come by last few years...expect to pay top dollar for a used carb unfortunately.

                  You likely don't need a new carb - there's plenty here to help. Tell these folks what you're seeing and you can probably get the issue resolved easily.

                    350 to 500 used on eBay for a carb

                      If you are more specific on why you think you need a new carburetor, it's very likely the folks here can tell you how to easily rebuild it.

                        I thought the gas was leaking from the Accelerator pump that has a tiny oring that may have failed. I replaced that assembly. Still leaking gas. from air breather. Please forgive the ignorance, I am learning.

                          Mine had intermittent flooding as well, out of the breather...changed the needle float, and the oring, don't skip that step, it is crucial. And the small oring in my kit was the wrong size. Took my carb to O'Reillys and they just gave me the correct one.

                        Where are you located? What about bowl gasket ..is it ok?

                        Is carb all stock or has it been jetted? What year bike and how many miles?

                            You absolutely done need a new carb...just couple gaskets and maybe a good cleaning. I think there are some members in your area...maybe one can assist in person?

                                    Check your float level, the float needle & seat, and the o-ring for the float seat. You will have to pull the seat to replace that o-ring. If the float bowl fuel level is correct and the seals are good then you might want to replace the rubber boot on the accelerator pump rod. You can get that boot from a Mikuni HSR-42 parts list.
