I have completely cleaned the carb on this stove. I have made sure that the in carb filter is clean. I need to know how big the oil feed line to the cumbustion pot oriface at the pot must be, as I have reamed the port out with a coat hanger, and it was quite visable when look in from thet top downward, is this adaquate, as the stove seems to run a about 1/3 of oil volume, in the bowl?
