I am new to these rotary engines but a life time backyard mechanic. cant seem to get this low miles 84 12 A to run strong, it starts easy idles good don't smoke or make any weird noise but you really have to put your foot in it to get any power. I have been over the normal tuning things,I have never driven a rotary be for don't know how there supposed to perform but until I kick in the 4 barrels its a real dog an even when I have it floored I think it should do better, if it where a piston engine I would be looking for a jetting problem, I don't think that is the trouble hear. could it be a plugged up catalytic converter ?
