Question:

My Spark Plugs Were Wet With Gas, Flooded. Check It Out, Temp. Sender?

My car is a 1972 Chevelle Malibu 350 5.7. Anyway, after replacing all the parts that are vital to getting a car starting (not driven) and draining the gas tank and filling it up with fresh gas, the car would get really close to starting but wouldn't fire all the way. So, checked fuel. It's getting fuel. Checked spark next, yeah... soaked wet. Why is it flooding? The plugs are out right now and I'm going to clean out the motor by turning it over until everything gets out of there and then do the compression. But what causes it to flood? Temperature sender? Fuel/air mixture on carb or what? Let me know! Thanks

  1. You have likely washed the cylinders down with gas, this can decrease the compression and make it hard to start, add an ounce of light oil (transmission oil  or 5W30) to each cylinder then crank over, the added oil will help seal the rings and provide some more compression, also dry the plugs and make sure not to pump the pedal, a static position works better, and it will be less likely to flood.


  2. more than likely you r pumping the carb ,,each time u press down on accellerator it pumps gas,  hold down the gas petal and crank engine over, may have fouled the plugs by now change them, temp sender has nothing to do with wet plugs

  3. Don't pump the gas paddle before starting the car, the 1972 car uses carb, not fuel injection system. That's why the plugs were flooded. If this happens, remove 1 spark plug, use a match to burn out the gas and reinstall it. This would do the trick to get the car started.

  4. The choke needs adjustment.  Hold open the choke butterfly, I normally stick a screwdriver in there.  Push the accelerator pedal to the floor & start.  Once the engine starts, remove the screwdriver & let run until warm up.  

    Prior to starting once the engine has cooled, remove the screws or drill out the rivets on the choke assembly.  Turn the black cap so the choke butterfly is slightly open.  Tighten the screws & start.  Hidden below the choke is a fast idle s***w, may need adjustment.
