75 chevy c10 flooding excessively i have replaced float and rebuilt carb can i abandon thermastatic choke

Your carb is needing to be rebuilt the seals and float and valve seat may be damage. The float opens when the fuel level in the carb is low. If the valve seat is damaged or the float is not working. Gas can keep pouring into the carb resulting in extra fuel. Till the engine stops and fuel pump pressure stops pushing fuel it will keep pouring fuel and will not stop till rebuilt correcting the problems. Buy rebuild kit and rebuild it or try junkyard and replace it.

excess fuel is not jets but the float needle and seat has material that is not allowing the needle to seal on the seat
check pump pressure as the pressure regulator may not be working causing excessive pressure that the float cannot control

Carb float bad or dirty needle seat leaking.

carb ajustment is off--issues in the float causing it to flood--cud be sticking--get a haynes manual or library sec629 has shopbooks

Not really a quick-fix for that...NEEDS A REBUILD KIT...

I would like to know what is the running tempreature of the vehicle, if the engine is running cold at all times then the computer will dump gas thinking the engine will die, check the O2 sensors and see if they are in range, also check the fuel pressure and it should be in specs last time to look into is the fuel pressure regulator. I hope the air filter is replaced.

Carb needs rebuilt, Auto choke not working properly. Be easy on the starting fluid you can easly blow a hole in top of piston.

Is the choke operating properly? You say the current carb has an electric choke, so I am assuming the original carb did not have an electric choke. If that's the case, have you wired the electric choke to a power supply?

Your float level is to high when you put the kit in they give you a float adjustment gauge,you will have to pull you carb back off and reset, but before you do that what is you choke set at if it wrong it will flood too,But if it set right you can look down your carb and you see gas dripping your you float is to high

Hello!


if you have a carbuerator unit on her, i assume you a refering to the fuel overfilling the bowl and flooding oiut after vehicle is shut off. this can be caused by a worn or dirty needle for the float, or possibly the float itself has ruptured and is partialy submirsed allowing excess fuel to enter the fuel bowl. i believe you may have a 307 or 260 engine that came with a rochester 2 barrel carb. there are unly a few screws on top of this carb and is quite simple to check...just be careful to place all pieces back in same position removed from...although with that age, the gaskets will likely tear when taking apart. it may be worth your while to check into a complete replacement from NAPA. anyways, once the 4 or 6 screws (cant remember) are off from top of carb (i suggest having the carb removed from engine as if you drop a screw into throat of carb and the engine ingests it..its bye bye engine)...the float will be exposed..carefully lift it out paying attention to the needle position once out...be carefule to not bend the tang that needle hangs on as this is you float depth that sets the volume of fuel allowed in bowl. and shake it to see if fuel is inside float. if so, replace it..if not, you may be able to spray carb cleaner into the seat that float needle sits in and wash off the needle itself..reasseble and recheck performance..also it is a good idea to replace fuel filter when carb is off...i hope this help you...good luck!

ps your 4 thumbs up is much appreciated
