"hot reading"??? sorry, I am new to carbs. I can install it, just don't want to get a crappy tune on it. Are jet's easy to install? I am thinking about buying 2.5 Max fuel filters to, since the carb will be off. The current fuel filter is probably horrible since its also original. It will also be easy to get at now! (well easier). I heard that Websters run best with 2.5 pounds max Fuel filters, is that true?
