Sure sounds like it's a vacuum leak. I'll attach a guage and check.
Here's a question: If I spray carb cleaner into the carb throat, is it supposed to bubble out from around the throttle shaft? I CC'ed it when the motor was hot and I saw it bubbling out from around the carb base and the throttle shaft on the passenger side of the carb (where the choke's arm attaches to, opposite the throttle arms).
The carb is still fairly new (<2 years) and has less than 6k miles on it.
Trouble is I semi stripped one of the carb studs so I cannot really clamp down on it. The other 3 are fine. What can be done? I was thinking to crazyglue gel the threads and permanently put that one stud in. I've tried plasteel but it is not effective.
