Hey Martin...it is indeed. Love the rig though.
It idles fine once the engine is at full operating temp, but doesnt hold idle when cold. My stock '76 only needs choke for a minute or two for cold starts. Could it be the aftermarket headers that warm up more slowly because they are more separated from the intake manifold than OEM? I also might have created a leak at the base of the carb with the new gaskets. I also suspected getting something stuck in the idle circuit during the rebuild, but replies to my idle circuit thread on ih8mud suggested a vacuum leak. Who knows. I'll get it dialed in soon.
Anyway, it is fun wrenching nonetheless. I'm just splitting hairs at this point. I'd drive this puppy to Alaska tomorrow if I had the time!
