I picked up an IDC 540 Supreme trimmer which has a Walbro WT124 carb and a round Tillotsen primer bulb. The primer bulb cracked and I need to find a replacement. Also, the diaphragm seems very stiff and no fuel is being pulled in. Does anyone know where I can find a new primer bulb and diaphragm? Thank you.

Also, who is IDC? "Inertia Dynamics Corp" isn't very visible on the web.
