Re: Do I need to ReJet
Carbs are designed with jet sizes that allow the right amount of fuel for the amount of air flowing through them. You can get real technical about exactly what happens, but I prefer to keep it simple. Trust me the carb has no idea what size engine it is bolted on. It only knows how much air is flowing through it. Carbs are designed to be accurate upto a certain maximum air flow. If you go beyond that point the carb becomes inacurate. Rejetting is only a futile effort to correct an undersized carb problem.<br />I would say it was unlikely that the carbs are to small for your engine. Are you having any problems reaching max RPM? Is you engine overheating at WOT? <br /><br />More technically, "altitude" would be a more viable reason to rejet. The airflow through the venturi actually causes a low pressure in the venturi, thus the fuel actually gets pushed from the fuel bowl throught the jet into the venturi where the air flow pulls it into the engine. Have you ever notice that every carb with a fuelbowl leaks when you turn it over. The fuelbowl is vented in order to allow atmospheric pressure to remain constant in the fuelbowl.
