I have a 81 Chevy c/10 Scottsdale with 350 Pontiac motor it cranks hard but will start should I get a bigger battery and I know the starter is bad cause the solenoid pops out are these my problems

fix the starter solenoid problem or get a heavy duty starter motor for the engine They spin the engine easier and faster than standard units
Next for a V8 350 I would be using a 750 cca battery or the next biggest battery that fits the carrier
check the ignition timing and adjust to 12 degrees BTDC as more than that makes for hard starting

either the float is sticking, when it is running use the back of a screwdriver and rap the bowl and see if this helps, or the jets need adjusted, start with the right one first, turn in untill the motor starts to lag then open it up untill the rpm stops climbing, do the same with the left one also, see if this helps. let me know.

1970 CHEVY IMPALA CUSTOM V8 350 eng. carb. rochester 2bbl. chokes itself then dies, a few times seems okay drive few miles then an dies d takes awhile before it starts or have to prime it any...

Sounds like you either have the float level set too high or you have debris getting into the needle and seat. To clear needle, disconnect the fuel line and divert it into a large container and allow the engine to run 'till it runs out of fuel in the carb and stalls. (use a length of rubber fuelline attached to the steel line to do this) Once it stalls, re-connect the line to the carb and re-start engine. The new fuel rushing into the carb shouls clear any debris.
If that fails to work, remove the top half of the carb (you can do that on the car) and check that the float is not adjusted too high and manually clear the needle valve.
I generally remove the stock filter in the inlet and use a larger plastic or metal inline filter in the line itself. Just make sure you locate it somewhere where it won't get really hot or interfere with anything that moves (alt, drivebelt etc).
Needing to prime the carb does not indicate a flooding condition though if it's running out of fuel, while running to empty carb, check the flow rate. It should pump about a half gallon of fuel into the container before it stalls.
Pressure should be about 5-7lbs running. Also check that the line to the tank isn't leaking. If it is, it will **** in air and stall the engine for lack of fuel. The mechanical pump and lines are a very simple system...something I mentioned here has got to help you!
good luck and if you have any follow up questions I'll be happy to help!

Carberator problem - holly carb on chevy 350 motor

You are correct, there is a float inside a holley 4 barrel fuel bowl.
Is the electric fuel pump regulated? If the fuel pressure is above 8 lbs, you could run into this issue or the float / needle / seat could have a problem or miss adjusted.

By the way, a 2007 GMC is not carbureted so I assume this is not the vehicle or it has been modified.

Good luck.
