i loosely wired up the AFR gauge into the rover to get a baseline setting, also handy as I'm using a rover / Bosch sensor too
after driving the rover for a week I've concluded that its taught me not a great deal ;) well that's not strictly true but i found out no matter what i do to the car i can not get the gauge to step into the "normal range" with it just sitting at the end of the lean scale (no wonder its got no power ) all wired in [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01738.jpg[/IMG] so after wiring it into the gauge i was happy to see it sitting to the end of the normal range towards the rich during cruising [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01745.jpg[/IMG] a little richer under more acceleration [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01746.jpg[/IMG] and lean on the over run [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01743.jpg[/IMG] this is pretty much spot on, especially since its a narrow band AFR gauge and sensor so its not detecting anything way out either end of the scale, so for a first attempt at carb jetting its spot on other things I've noted though is it goes haywire with the choke out and can go lean at WOT before the fueling catches up as the revs rise, ill either need to change the pump jet or accept that a carb is still hit and miss at best. I've a matching vac gauge to go in next to it tomorrow so i should get a good idea as to what the engine is up to. other news, I've replaced the stat for a lower one, but first the stat housing looked a bit shabby [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01733.jpg[/IMG] [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01734.jpg[/IMG] so i blasted it [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01735.jpg[/IMG] [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01736.jpg[/IMG] like new painted the hose ends with tick polyurethane paint to prevent pitting and seal some old minor pits [IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01737.jpg[/IMG] engine seems a touch cooler now so smiles all round -- You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
