Have been working on a '72 F7 project and have verified spark, gone through carb (checked float height, cleaned all jets, replaced jet o ring, etc...) lubricated all cables, hooked up auxiliary gas tank and attempted startup. The engine starts hard with choke and when it fires it runs at a high rpm, will not idle down, and requires fiddling with the choke lever to keep going. I checked throttle valve and it isn't sticking and with throttle off it's in the bottom of the carb housing. Also checked idle adjustment on top of carb and it is turned almost all the way down. I suspected a vacuum leak, so I plugged the vacuum line from the carb that goes to the petcock (which is not installed as I am utilizing the auxiliary gas tank). This didn't solve the problem. I checked the carb holder and found that the carb fits on it rather loosely, not snug like I would have thought it should be. So, I ordered a new carb holder, thinking that over time the rubber on the carb holder may have shrunk or deteriorated somewhat. I read on the Junkman's site that it is recommended to remove the fuel drain pump and block it off, because when these fail, a vacuum leak is created. I guess by blocking it off that means just fabricate some sort of plate to close off the opening. This bike with only 3,600 miles spent most of its life sitting, so I expected some difficulties getting her going. Would anybody with experience with this issue care to provide any advice on what all I should be looking at in addition to what I have done already? Would greatly appreciate it.
