I recently picked up my 1982 T25 (Leisure drive) and one thing I have noticed is that it seems a little down on power, especially when faced with a hill

I had a friend carry out a service (currently my engine knowledge is limited to knowing that it is in the back of the van) and while doing so he noticed that the left carb was missing part of the plate (pic attached).
I guess my question is, could this be causing the issue, or could it be any number of things that need to be looked at?
Many thanks in advance for any help, and I apologise if this has already been talked about / answered.
