OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Trimmers and Brushcutters Two Stroke Trimmers & Brushcutters Walbro WT124 carb, Tillotsen primer

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.

I can furnish you with the primer bulb,
I D C is a progression of owners starting
from Outboard Marine, then, IDC, then Ryan,
and now Ryobi, the basic machine hasnt changed through all these owners

Thanks for the information, Bill. Ryobi is mailing me an IDC manual. Please email me details on the bulb.

Does a stiff diaphragm sound like the fuel problem? I forced gas into the carb and it ran for a few seconds.

Tod,
If the diaphrams are stiff then you need to replace them as well as the fuel filter and your problems should be fixed.
