twin running rich on one cylinder

I have an evolution 116 that is running rich on the right cylinder At idle it seems to run fine and full throttle is good but has a lag when you advance the throttle in the midrange it is more pronounced in flight The carb has a line back into the fuse for carb equalization

I bought it used and it has been changed to rcxl ignition never had an engine do this before could ignition be cutting one cylinder out in midrange?

checked the plugs left looks good but right is definitely rich black and oily

its turning a falcon 29 x 9 at 6500 mej 30 x 10 at 5870 on mufflers but i want to get this fixed before I put the pipes on it idles at 1100 no hesitation after 2 or 3 mins of idling so looking for ideas

todays test will be new ignition and if that doesnt work bypass the tech aero ibec no spare plugs on hand but ordered some for next week

any ideas welcome
