so i have a gslse motor carbed in my rx3 , it looks like some stock 4 port carb anyhow i wanted to see how the guy had this thing rigged up and why its so friggin slow,

anyhow heres the answer the ports are so badley matched theres like a 2cm wall around all the port holes

 

OK so it looks like some one built there own lower intake and didn't take in to acount the rotary in take vales, so when the 2nd in the carb tryed to come on there was no high speed air draw to subport the flow, should have use the stock lower complet with a custom upper addapter for the carb

 

ya this is a spacer between the stock 4port manifold and carb to the 6 port motor, that this guy made and its friggin horrable
