She starts up fine and idles nicely. The problem is that once I lay on any amount of throttle the RPMs shoot up to between 5 and 7 thousand, and stay up there even when I let off the gas
My throttle cables and throttle mechanics on the carbs all work fine, opening and closing in accordance with the throttle itself.
The only explanation I could think of, is that there is a vacuum leak somewhere.
So I ran with this theory, i've had my carbs in and out a couple times, so I guessed the chances of me making a leak someplace were likely, and potential holes could be anywhere on the boots, the surge tank or the connections from the surge tank to the carbs.
I gave her an earshave, because I'd wanted to anyways for one, but mostly because as far as I could tell, the earshave procedure would cross off any possible vacuum leaks except for the boots themselves.
In the process of the earshave I removed the carbs and examined the boots, they looked fine, then I took great care to put them back on the correct way.
Well I just finished the earshave this morning and started her up and I still have the exact same problem.
