The only real problem you are going to run into is that the needle valve will now be between the prop and the muffler. This is going to make it difficult, or dangerous, to adjust the needle while the engine is running. You will be reaching in between a spinning propeller and a hot muffler to make your adjustments. This is a recipe for disaster if you ask me. However, if you can put an extension on the needle where you won't be near the muffler you should be ok.
