"Patina" The 1973 CB175 Cafe Racer

Can anyone tell me the difference between these two screws on my carbs and what each does? The book says one is a throttle screw and one is an air screw. What are the stock settings for each. They are the stock carbs.

The recessed screw on the manifold side is the air screw. Usual starting setting is between 1.5 and 2.5 turns out (depends on the carb and I'm not overly familiar with yours).

The other screw doesn't look like a throttle screw to me, but if it is, it's used to sync the carbs and set the idle.
 
The best manual I have seen is the 125-175 cb shop manual I have read it cover to cover. It appears it was a tutorial for the honda mechanics. It is amazing! Our cb200 manual is in no way close to the detail. It is basically a technical journal but the 175 shop manual is a step by step who what where and why.

That's an amazing 200 pages. What's the difference? I guess ones an owners and ones a shop manual? Very cool they used it for instruction. It's very much a text book.

Not much of an update but my throttle from Les Vintage on eBay came in today! Solid construction, the cable says motion Pro and I bet the housing is too. It's a quick turn with a shortened cable.

Ok guys, another carb question...

Can you tell me how I know the slides are in the right carb? I think the correct question to answer this would be: does the cut side of the bottom of the slide go on the inlet or the outlet of the carb?

Other than that, the slides themselves can only go in one way, correct? Otherwise it interferes with the screw and won't fall down into place.

Is this right?

By cut side I mean the diagonal slice on the right side of the slide in this pic...
