Changind potiometer value

Greetings, I have a small circuit, in short, a multi direction PWM circuit, with a 100k pot. Here is the link if you wish

Attached is a cutout of the 100k pot, is there any way to change the value of the pot? Reason is, my 100k pot doesnt have center stop, which is important for this circuit. I have a 250k pot that I would like to use instead.

The circuit will work fine with a 250k pot if the values of the two resistors connected to its ends are also increased 2.5 times.

Hey thanks, will give it a shot. I would have thought bigger pot, smaller resistors.
