Hi folks, sure could use some advice and I came here due to the reputation of racingjunk - if I can't fix this, I may be bringing a car to Monroe!
Engine is in a FFR Mark3 Roadster (cobra replica) so very light car. 5000miles on it, I just bought it and it will scream like every guys dream! Problem for me, I like to lug cars and have good drive-ability along with a good lumpy idle and for this car, I can live with a little less performance - yes I said it
ops:
So, I'm sure the carb needs some cleaning and a good tune as it's not been driven much lately. It starts, runs, idles great but does smell rich at idle. It feels dead below 2000rpm then it pulls like a horse to 6000 rev limiter. And in my 4tanks I'm getting 10-11mpg (don't like that) and that's just around town no real racing stuff. One local shop suggested starting w/ tuning the carb on their dyno. I tend to think it's either over carb'd or the cam is too hot for my needs. And if I want better gas mileage and more low end torque and drive-ability, maybe I need a different intake (this one for high end), cam swap, a carb swap (vacuum sec or single pumper) or maybe a new, milder engine (god I hope not). I love the car, just need a more torquey engine.
Advice Appreciated:
It's a Ford, 3.73 Rear, T5 Super Duty Trans by Levy Racing 0.8 final ratio.
