Set start number on 7490 circuit
First, since you are only counting from 1 to 5, there is no need to specify a BCD counter.

Second, and more importantly, don't use a 7490 for almost anything, especially an application in which you are going to operate on the outputs. Instead, go to something like a 74161 or a 74191. These have a synchronous clock and either a synchronous or asynchronous load, which will take a good deal of the potential heartache out of decoding and feeding back outputs.

Third, you need to provide a POR, Power On Reset, which will force the counter to the desired state when power is applied. This can be as simple as

Note that the inverter should almost certainly be a Schmitt Trigger, with the 7414 as the standard part.

If you do go to a better counter, you will find a conflict between your POR and a feedback reset. POR is easier with an asynchronous load, but feedback loads will be far better served with a synchronous load.
