Stumble under load at 3000+ rpm
Hey guys, looking for some help... I have a 86 Mazda b2000 with a 1977 13b block and 1979 rx7 transmission... had the carb adjusted so both front and rear glass is right at the dot. Was running good when I had out earlier this spring until it snowed again...custom headers so doesn't run well at all in cold. I've replaced plugs, adjusted carb floats, new 5-9psi fuel pump, new fuel filter... still stumbles hard on acceleration but idle fine. Any suggestions?
