My CB175 has had some problems for the past year or so. It gets stuck at high revs, have to downshift to get it to come down.
I thought this might be a carburation problem. I went through Steve/Spring66's advice about CB175 carburetor adjustment. I thought I'd try this before doing a full carb cleaning.
Adjustments to the left carb make no difference. Air mix screw can be all the way in or out with no noticeable change. No adjustment to the throttle stop screw makes the bike rev higher, though taking it all the way out causes it to cut off.
Hand placed behind exhaust pipe, very soft "pressure" from exhaust out of the left side. Right side is strong.
(This may be unrelated) I get a sound like a spinning free wheel after I've been accelerating for more than a few seconds. Not loud, but it's there, seems to be coming from engine/transmission. It continues even after I'm off the throttle, but eventually stops -- like it spins itself out.
Should I just begin by pulling and thoroughly cleaning carbs? If so, I welcome any good videos or photo-heavy carb cleaning guides.
