Mercy Rule Help

[Remington]

Our state has adopted the "mercy rule" for our lowest level of varsity basketball. The state has said a running clock will be used if a lead is 30 points or greater at the start of, or reaches at any time during, the fourth quarter. The clock would only stop for time outs or injury.

One of our officials had a game last night where the score was 30+ and A1 was fouled in the act of shooting. Before the free throws, Team A called a timeout. The clock stopped, but the officials weren't sure when to start the clock. Should it start when the timeout ends or when the free throws end? I visited with the state and they didn't have an answer yet.

For those of you with similar mercy rules, what is the ruling in your area?
