Tracy,
When I do a full tune up on a customers engine, It usually takes me approx. 2 to 3 hours.
That includes, changing the oil, (filter if you have one) Adjusting the valves, changing spark plugs, rotor, cap and points if you have them. In addition that includes adjusting the carb's/linkage and setting the timing.
Multiply 3 by the hourly shop rate plus parts for a total.
Parts including rotor, cap,points, valve cover gaskets, oil and filter usually cost under $50.00
