Re: Carburetor hesitation
i had a similar issue with stalling after running for no appearant reason. it turned out to be a worn HEI rotor. The tip of the rotor was so worn, a large gap was created between the tip and distributor contacts, resulting in a weaker than normal spark to the plugs. funny thing was it had to get hot to fail.
replaced the rotor and hasn't happed again. worth a look if it has some miles of use on it.
