So did you buy it Carl....................or were you 'fooled' by his description and decided to pass on it?
Here's my early production Dayton branded Poulan 245SA. You can see how much taller the front of the 245 tank top is compared to the 306 tank top. The AF covers have different part #'s too. No doubt to match the different 'slope' of the two tank top types.
Don't forget the 245 used a taller front handle also.
