I run a Clifford myself and they don't make the same low end torque as the Offy, they are set up to flow big air so the advantage they have is in higher rpm range. I love the Clifford, it gives the engine a totally diferent sound than the offy when you are at high rpm. As far as the fuel goes you may be right, the setup you are running is often too rich, still it is better to know you are too rich and then go leaner than to go leaner on a hunch when you may already be lean. So far we only know that the idle circuit is rich.
