    On my choke pulloff, it has an "allen screw" to adjust it on the rear, so... what does it do exactly? Screw it in or turn it out for.... if I do that, does that adjust the choke rod length? Wouldn't bending the choke rod serve the same purpose? Or do I need to also bend the rod? My carb has an electric choke and I think I have it set correctly. The problem is that during cold start, the RPM's are low, 500 RPM until it warms up. I do have the fast idle set on the high cam correctly and when I fire it up, it idles around 1500 RPM until I kick it down and then again, the RPM's idle around 500 until it warms up even more. As soon as I drive of of course, the fast idle kicks down, no way around that, so... suggestions? Thanks!

    eelctric choke have a screw underneath the aluminum round choke housing, tighten it to speed up cold RPM,
    do not bend any rods!
