  • Patent number: 3957930
    Abstract: The present invention relates to a carburetor, and more particularly relates to an improved carburetor for a high-performance engine. Improved performance is provided in part by fixedly positioning the fuel dispensing element in an optimal location of the carburetor's airstream -- regardless of how the airstream varies with the engine operation. Moreover, the disclosed carburetor has a structure that minimizes or eliminates internal flutter that previously produced inconsistent fuel flow. The disclosed carburetor further includes novel fuel purge valve means that is automatically operative upon engine shut-down to drain the remaining fuel from the carburetor so as to prevent flooding during subsequent start-up.
