Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
the way i set the float on these is to set it where it is straight across,level] with the carb...most times this problem isnt the float,it is the needle valve seat,it may have some debies in it[it dont take much]..this is sometimes caused by a rubber fuel line being slid onto a mtal line,it will whittle some of the rubber from inside the hose then go right to the needle valve seat,,,so,clean out the seat,the filter chamber and the float bowl,,,it is a good idea to have an external filter in the line right before the carb,,again,,if using a slip on line with clamps,be sure to oil the inside the line with wd40 and slide it on easy making sure not to scrape the inside of the line..

Hi my name isXXXXX will assist you.
Do not use fuel line from the fuel pump to the carburetor. This is a Coast Guard violation the fuel line from the fuel pump to the carburetor must be a steel or stainless fuel line. Rubber hoses will deteriorate and burst under pressure spraying the raw fuel into the bilge and engine compartment. This is an explosion and fire hazard.The float adjustment is with the inlet needle closed the float is parallel with the carb body. The carb leaking at the base is flooding and the float is not closing the inlet needle. Here is the procedure the float level is 15/64.
