TBI diffrences
I posted this a while back and someone had said that all the 305 350 TBI units were the same. Well I found diffrently. I was looking on Ebay for a ported or overbored TBI unit and thay are available but the ones on ebay did not look like the one I had modified. Heres some Pics of the 2. My question really is... Can thay overbore the one with the exposed spring on the TPS side. See how much material that isn't there? I had a custom linkage welded on the one I ported already would like to use that one. But I would like to get it bored to 50mm.
