Yes Jetts did bring up a good point about some models having the square plastic reed but you will see when the tank is removed.

One last point I neglected is if your have to replace a glowhead don,t bother with the standard, instead replace it with the high compression head (more power and easier starting). It can be identified by a ring of radial marks clear around the center terminal.

Sure would like to find a functional glow head for my old Holland Hornet from around 54 or 55.
