Need some advice concerning Generator issues

i've got a 2.5kva chinese "loncin" generator and a generator dude said i need a new AVR because when it runs, some of my lights flicker. the voltage output is about 200-210. now does anyone know of a place to get a good quality AVR? the ones i've found range from 200-2500 rs and i just have no idea what to get.

Another thing, if the gas pressure isn't up to snuff how do i get that fixed? do i have to get another line or can i just get the existing one's pressure increased?

thanks all.

u shal have posted ur problem in the generator thread. otherwise that is a very informative thread and wil certainly help u in solving in some of ur problems.
