new rebuilt dial in
« on: May 27, 2014, 09:09:43 AM »
 :)hi. just started to dial in my q-jet. it's a 17056202 (77 camaro). i'm useing a wide band and it shows 14.9 at idle, 16.5 at cruise and about 12 to 1 when i romp into it. cruise is a little lean but thats ok. cruise is at 2200 rpm and 17 inches of  vacuum, idle is about the same. set up is, 47k rods, idle tube .037, down tube .053, main jet is 72, sec rod da, idle bypass was down sized to about .050. upper idle and lower idle air is stock at .070. might try to get the cruise at 14 or 15. this is stol and not lamba. also have a 42j pri rod i might try. i had to raise the apt up about 6 turns to get these numbers. maybe a 73 or 74 jet will allow me toget the apt down a bit. this is a 250 horse 350 (thats what i was told) thats mostly stock. also would like some advice on a power piston spring to use. thansk in advance.
