My experience with pine tar in general is extremely limited, but be careful
if you try--it's probably going to spit little bits of hot tar at you.

I was introduced to pine tar as a binder to make cross country ski wax
stick to wooden skis. It's really sticky and really hard to wash out! It
does a good job on the skis. It becomes less viscous when heated. No
insight as to effectiveness in rocket fuel, but wear clothes you don't care
about.

I googled it and it seems resin, pitch, rosin, and turpentine, are all
derived from the pine sap with greater or lesser degrees of processing.
Pine tar however, is made from carbonizing the pine wood itself and is
described as "liquid smoke" by some. I suppose all of these could be used
in rocket fuel as they all burn, and are gooey and sticky. Even turpentine
can be viscous and tacky.

Never thought of that...I cut some trees for firewood that are oozing all
over. Wonder how much is needed for a 6 grain 98mm motor?
Perhaps thin down with turpentine?

Has anyone tried pine resin or even unprocessed pine sap in their rocket
fuel? I thought it might mitigate some of the brittleness of sugar. It is
flexible, flammable and can even be free if you have access to
accommodating trees.
