I need two screws to hold a primary butterfly valve on the throttle valve shaft.
The carburetor is holley manufactured for motorcraft.
1986 F250
The heads broke off the two screws on one valve. The heads are currently
tinking around in a cylinder. There might be some valve damage.
While I was trying to figure out what the noise was the truck started
running rough and the tinking sound was very loud in the exhaust.
I guess one head was or is holding an exhaust valve open.
Any ideas where to get the screws. Besides Holley?
Thanks
