Re: [Quantum Owners] Re: 40's on Pinto Xtreme: help!
interesting here is the recommendations for idle jet size is consistently 50, with differing air corrections to adjust the idle air mixture and the progression. Mine are 60s and are too rich. As Russell says, emissions can even be reached on my 60s but it runs like a dog on this setting.

Re: [Quantum Owners] Re: 40's on Pinto Xtreme: help!
Ian, Don't forget that they do an emissions test on the IVA, but if the jetting is for a lower cc engine it should be OK. My car was not running particularly well for the IVA and still isn't I can't get it to tick over low enough.

Thanks for the responses: I have gone through the carbs and have a note of all the jets (but I have left it at work!)
