After replacing new carb insulators and rechecking for leaks it still revs to 3000 rpm after a few miles of riding. I noticed on another set of carbs there is a plastic "T".between carb 2 and 3. The carbs that are on my bike has a piece of clear tube between the 2 and 3 carbs with no vent hose. Could this cause the revs to go up?
Can't wait to get this bike finished so I can start another one Just to drive my wife nuts.

I am nit sure which carbs you are talking about, but if the float bowels were not venting, the engine would most likely starve for fuel and die.

Is this on the top or bottom of the carb rack? If its the top this may be for the vacuum assist or SOS, if it is and its capped off this is a good thing.

Tools, the arbs that has the plastic "T" are on a set of carbs that I bought off Ebay. They are from a 1979 cb750L, the same as I have on my bike. When I disabled the carb from Ebay I noticed it had the plastic T between no.2&3 carbs and on my carb have that has the clear tube between 2 & 3 which I don't think it's factory.

I am not that familiar with the CV carbs used on the DOHC engines to really answer questions about them. However right above your post is this thread that is pinned at the top of the section. http://honda-cb750-s.456789.n3.nabble.com/Cleaning-and-adjusting-a-carberaters-best-videos-for-dummies-This-ought-to-be-pinned-at-the-top-td3905817.html This thread should have pictures of how the carbs should be set up, that might answer your question.
