Thread: CT90 Carb and Throttle cable Help!

I just put a new carb on my 1971 CT90. We installed it no problem, but when we put the throttle cable and pin in then started it the engine revved extremly high (with the throttle closed) and wouldn't change when I opened/closed the throttle. The internet hasnt been very heplful so I was wondering if anyone had any ideas as to what the problem might be.

Note: We did not change the cable or the topset.

You most likely have the slide 180 deg off.

barry's got it i reckon, common mistake for a noob(we have all done it atleast once), carb barrell fits in 2 ways, only drops down enough in one of those positions though. If you have the airfilter off the barrell should drop all the way down leaving only a small(like 1mm or so) gap. It the barrel was installed correctly then perhaps the cable is too short.

I just went through the same problem with a bike and it turned out to be the cable was to short.
