yeah they needed jetting and a minor overhaul/clean up. They are not suitable to run on a K10 as they are, as it will cause engine damage. I forgot to say, but they are now upfor sale. open to offers.
Ed, I may be interested..
What carburetors are they?
Would they include the manifold?
How is the manifold constructed?
Why will they cause engine damage? Jetted too lean?
What needs overhauling?
And how much?
