I've been thinking about putting smaller jets in my carb to experiment with fuel economy. At the risk of starting a thead of people bashing me and captain carburator I do have a question to ask. Would it be possible to sort of check my mixture by inspecting my tailpipe? My guess is a tailpipe with a thick layer of soot (whatever its call) inside would be running too rich. A tailpipe with no black soot would be running too lean. I"m wondering if I can lower my jet sizes and check my gas mileage and tailpipe until I find a jet that I am happy with and that won't run the car too lean. I'm sure I could also check spark plugs but checking the tailpipe only takes seconds. On Fri, Apr 13, 2012 at 9:53 AM, Stephen Rice <stevedmc@xxxxxxxxx> wrote: > $300?
