For clarification, avgas is 6 lb per gallon. Useful load is defined as gross weight minus empty weight. That being said, you need to recalculated your numbers. More importantly, the LSA class was and is not intended to support folks that are 300 lb plus (almost 25% of the gross weight for 1 person!). You need to look at Part 23 aircraft.
The Skycatcher can support 2-200 lb folks plus 12 gallons of gas. Given the class, that is not all that bad.
As for the unrecoverable spin being the result of being tail heavy, that was not the case. The spin was being conducted in the aft range of the cg. The failure of spin recovery was to due to inadequate rudder authority, which was corrected on subsequent aircraft - i.e. - added ventral and rudder area.

The max TO weight is 1340 pounds
the empty weight of the standard model is 843 pounds
The fuel capacity is 24 gal * 6.25 pounds is ~150 pounds
so useful load is 347 pounds.
Most people, now a days, are 200-250 pounds.
I.E. there is not enough payload for two typical people.
And with my 310 pounds, there is 37 pounds for the instructor.
Unfortunately, Cessna seems to be using the 'standard individual weight of a
male adult person, as defined by the FnAA Rather than the reality.
I'm not familiar with the CG range, but very likely, a full payload (347 pounds
+ full fuel would result in a tail heavy condition.
(remember the testing where the test pilot could not get the plane out of a spin
because it is too tail heavy?
