After trying many many things. I am giving up on fixing this issue myself. I took both cars to a retired RC guy who now owns a small engine repair shop. As it turns out it was not a carb issue or trash in the fuel cell. with the carb settings on 3/4 H and L, the engine is not burning all the fuel. I can literally pour the excess out of the exhaust. I am leaning now toward the coil or the plug itself, but don't want to just throw money at it. So he is tuning them for me. I'll update again when I get my results.
