idle screw size anyway here is what I found.
thread size .7mm
length not counting the head of the screw is 11/16" long
the end of the screw is not threaded for about 3/16" and there is a about a 45 degree angle on the end.
spring is about 3/8" long uncompressed and the inside dia. about 3/16"
you should be able to get the parts at a hardware store or nappa auto parts store.
