Pedal adjustment problem

[bird_4_3]

Have an 01 CC 48v Series cart. Cart has always been super slow and I decided to change out the pivot rod and put a new MCOR (the latest model) in my cart. Well not knowing what I was doing I did not adjust the pedal the correct way....what I mean is the cart when I would take my foot off the gas and just let it sit would want to creep forward. This eventually burned up my motor because of the constant use when I had the brake on. I am not all that upset about my mistake, I wanted a new motor anyway (wife is still mad lol). I have ordered a new motor and have it on the way. My question is how to I adjust the pedal to make sure this does not happen again. Is it a pivot rod issue or an MCOR issue?

Hope this make sense and thank you in advance.
