I can deal with a little bit of dialing in. We dialed in Snowmobile carbs, some of them three-barrel, some of them multiple singles, for years so that part isn't new and I know how to take it slow and one step at a time. I could partially mask a fault on the Dells by playing with jetting and got it to run OK, but there has always been something fundamentally out of whack that I haven't understood enough to cure it, nor do I have a selection of parts (other than a bunch of jets) to change basic airflow characteristics.
I just believe that these were never really "tuned" for my particular engine requirements from day one, like matching venturii size, air correctors, jet size, all that jazz, to what the intakes, cam performance and exhaust expect to see. All I did was buy a pair back in the mid-1990's, supposedly set up for a 2,110 right out of the box, when in retrospect I just got a generic pair of 40mm Dells (that I now believe might have performed better on an engine with a milder cam).
What really made me a believer in Dave at Blackline was that he asked for the head and cam specs and compression ratio, along with basic carb specs right at the beginning of the conversation and made a few comments as we went along that were dead on with what my air/fuel gauge has been telling me (and I thought it was just a cheap gauge giving me false readings). Without ever seeing the gauge in action, Dave told me what the engine should be doing and that's what the gauge said, too!
Anyway, I'm boxing them up, and, listening to Horace Greeley, I'm "Sending them West, young man!" to the land of Shake Tauffler to see if they can become born again for their second act.
