17057253 idle tube size
« on: January 21, 2020, 05:59:58 PM »
What was the idle tube size on a 77 Olds 350 carburetor? I'd also appreciate other specs like air bleed sizes if anyone happens to know them. Thanks.

I show they were .034.  Down channel .041
Mains upper .070 lower .030
Air bleeds both .069

These are just notes from same code we have disassembled and documented. Hope it helps.
