Wot fuel mixture is handled by jetting. The carbs are adjustable for low speed mixture which can effect idle speed. I was talking about the timing only being able to be set with the engine at 5K rpms. If you can only get to say 4500, then set it to 16-17 as it will advance some with more RPM's. Timing is probably the most critical aspect to that engine, and it must be set at the correct rpm's, with a good light, and you need to be certain the pointer is dead on tdc as well. I've seen alot of these engines come back from supposed top shops running like crap because they didn't set the timing correctly, so they set it low to be safe.
