I have acquired a Weber 36/36. I need the specs on tuning it and on the carb it self what is it exactly never seen one till now they look different from the common ones. One of my butterflys on top is missing is that ok and I bought it used. Will it be good for my Mitsubishi mighty max 2.6L? or anything else on what I need to make it work great on my 2.6L like do I need to go to a electric pump or what kind filter I need etc. Anything is greatful.
