No Scott, it is too small to use on the 306.
Poulan still shows part # 530031004 as still available and $7.20.
I dont have one myself, I just made one from a steel strap iron with two holes drilled and tapped for #10x24 screws to go into the 2 holes in the clutch and welded a 3/8's nut in the center of it.
But that trouble isnt really worth $7 I just needed it right away.
mark,
thats a good idea
for clutches, i've used a steering wheel puller with bolts and nuts at the right spacing, and sometimes, the bar that holds copper tubing to flare can be used with nuts, bolts and washers............
