Hi there!
New to the forum, so hope I'm not barraging you with too many things at once! I recently swapped a '62 170 for a '68 200, and am having issues with it idling correctly- running rough/stumbling a bunch at idle, but seems OK at speed. Here are a couple of things that I'm unsure of on this engine...
1) There are two lines coming off of the distributor, one in what I call the "normal" place, at the end of the vacuum advance, and the other coming off the top. I routed the one at the end of the v.a. to the carb, and the other to a vacuum source on the manifold- does that seem correct?
2) This all pertains to the carburetor- I've never seen this carb before-but I'm 99% certain it's a Holley 1940 from looking around on the internet a bit. What is the proper idle air bleed screw setting for this carb? All the way in, then 1, or 1 1/2, or 2 turns?
3) Second carb question pertains to the fast idle cam- for some reason it looks like it's missing a piece, but I'm not sure. Here's a link to a picture http://yfrog.com/1q64ij; does it look like it's all there? I guess I think there should be a screw or something going to the cam, to allow for adjustment.
Thanks for the time, guys!
