Id adjust your temps. 90 hot and 80 cool.Assist or force feeding is very stressful, to both you, and the snake.

I always wet a fuzzy asf, so it slides easier.. Hold the snake with my index finger and thumb and use ur pinky against ur palm to control the tail.
Rub the preys nose against the mouth an slide it in. I will usually push the hea in just far enough it wont fall out, then lightly push the jaws of the snake closed and set it down. Sometimes thats all they needed, thats the assist..

The force. Do the same as the assist but instead of stopping, u keep pushing. I use a qtip or something smooth, to prevent teeth marks in my fingers, push it all the way in, and then massage the throat up and down with a lil pressure, it helps stimulate muscle action. Lay the snake down. And watch it, it may regurge, i will usually not try again unless they are very very small.

I force fed one hatchling for nearly 2 months, it hadnt eaten in nearly 6 weeks. Was down to 40g roughly, even if he gurged the first 2 times, he got it pushed back in.. It was hard to do, often felt like i was causing more pain then helping.

I would always offer live prey every week over night before forcing in the am, this week he took for the first time on his own!!!!!
