Is this a G/K? Thanks for any input. Some characteristics are: Flat top generator loop, angled to the right when looking down the fuel tube. Bakelite base. Short pump clip arm. No date on the fuel pump attachment boss. External snap rings hold the arm, as well as the pot support rods. Jet is not marked, has a screen inside of it, and uses the sintered bronze fuel filter. Removable fuel tube cleaning cable. Note: original sparker unit was broken, and replaced with one that is nearly identical (same size knob as original).
