Andre McCollin opened the scoring after just 33 seconds but Wingate came back with a debut goal in the 10th minute for Leyton Orient loanee Freddie Moncur.
K's took the lead for the second time when McCollin notched his second with a free-kick from outside the area.
After Wingate `keeper Bobby Smith was carried off after sustaining a blow to the head and neck area, the visitors took over the game and it was no surprise when Billy Healey equalised in the 54th minute, taking advantage of a defensive error.
