Power valve

Sounds to me like you need basic tuning. That cam has a ton of overlap so you'll always have the fuel smell at idle and it has litle to do with the actual burn. For a base setup I'd say go with 38° total timing w/o the vacuum figured in. Initial 16°-18°. Centrifical should be "all in" around 2800. Once the timing is close, the carb.. Set base idle to the best lean idle at around 850rpm. When that's done, take a vacuum reading in gear. The power valves should be 2-3 numbers lower than that rating. It should get much more crisp as you get it leaned out.
