MC2100 has openings not covered by adapter plate
Was looking for some guidance here. I bought a used MC2100 off of Ebay hoping to put it on my 258. Pretty straight forward so far right. I did some research and bought the proper adapter plate and manual throttle. When I flipped the carb over it looks to have open areas that dont get covered up by the adapter plate, the guy at Napa(auto parts store) said it was a newer one and that might be the issue. Long and short.... can I use this one and if so how or do I need to go find another one.
