Ok, a friend of mine just bought a 65 GTO and is having me go through it and clean it up some (plugs, wires, clean the carbs, blah, blah). It ran pretty well before, but he wants to freshen it up anyway. The only issues he had were: sometimes it would idle high (1200-1500), but, only when he had been driving at highway speeds for awhile, and it would flood pretty easily when it was cold. Its a factory 3x2 Rochester setup and I'm not too familiar with that. I'm pretty much convinced the high idle is from all the throttle linkage probably hanging up somewhere...I'll check that out later. I've got the carbs torn down and I just wanted to bounce some stuff off you guys and see if I'm in for a headache.
Here's my questions- The secondary (outer) carbs have small holes (one per blade less than 1/32) in the throttle blades but no provisions for idle circuits. Is this normal?
On the primary Carb, when the throttle blades close, there is about 1/8" of the transfer slot showing. Is this too much? Also, the throttle shaft seems a little sticky when turning it with the throttle plate off the Carb. Any good fixes for that or do I have a trip to the swap meet in my future?
Also, he said the car would sometimes idle like shit when he came off the highway, then would kind of clean itself up after a little slow driving.
I know it ain't a boat, and its a bunch of questions, but I'm hoping some of you guys have dealt with this and can help me out. I know these are probably the reason why everybody runs single carbs, but it is what it is lol. Thanks in advance.
