Floods

This could mean gas is flowing over the top, out the vent, or even out of the throttle shaft.

Here are some possible reasons:

  • Needle & seat leaking.
  • Float leaking and filling with gas.
  • Fuel pump putting out too much pressure. Should be under 4 lbs.
  • Float rubbing, or catching because of worn float shaft.

There is too much air, or not enough gas.

  • Check for leaks around the throttle shaft (where the shaft comes out of the throttle body). This is caused by worn shaft. Re-bush.
  • Mounting gasket is leaking.
  • Not enough fuel.
    • Weak fuel pump.
    • kinked fuel line.
    • Non ethanol resistant rubber fuel hose. These can collapse inside.
    • Old gas has turned and coated the inside of the carburetor with varnish.
    • Plugged, or dirty passages.
    • Check the idle pickup tube. They are often plugged. Cleaners will not get them unplugged.
