When I was in high school back in the 70's and one of us had what we thought was a carb problem, but couldn't figure it out, we would switch out our carb for a buddy's carb that was known to be running fine. Fifty years later we do the same thing at my local Cobra club. In a lot of ways, we're still back in high school.  And every now and then a particularly frustrated owner, after bolting on someone else's carb and having the car run beautifully, will offer to buy that $400 carb for a grand or two.  Seriously though, that's such an easy test that I'd like to see you do it before you even spent two bucks on a power valve.  |
