Car is up and running but have a few problems!!
ok i just put the heads on my 454. i also just purchased a Demon carb and have that on my motor as well. ok so the motor cranks just fine....initial timing is at 10....total timing i have no idea because i dont understand that whole thing.....anyway the car runs fine except she runs really really rich....the carb i have has a 4 corner adjustment.....so i break out the ole vaccumm gauge to set her mmixture and the motors vaccum IS ALL OVER THE PLACE and still blowing out black smoke. now this is where i need help.....
1. do i reset timing....i know some 454's need timing set to 8....(My 454 is basically stock...mild cam and no insane compression)
2. seeing that my motors vacumm is all over the place tha leads me to believe that i have a leak....i have looked and dont see anything that might cause this....but you have any ideas i will look into it.
3. off idol does the advance of the dist. (yes i have hei...vacumm advance) have anything to do with how rich she runs
PLEASE HELP THESE ARE THE ONLY THINGS I CAN THINK OF.....I AM SO CLOSE AND I JUST WWANT SOLID VACUMM AND A CLEAN EXHAUST
thanx guys
STREETS I AM LOOKING FOR YOU
STREETS I HOPE YOU STUMBLE ON THIS THREAD......YOU ARE THE ONE THAT HAS BEEN WALKING ME THROUGH SINCE THE BEGINNING...AND YOU HAVENT BEEN WRONG YET....WISH I KNEW WHERE YOU WERE AT SO I COULD BUY YOU A CASE OF BEER AND BURN SOME MAMMAL FLESH IN THE YARD....I OWE YOU MAN.
ok...a little better but not good enough
ok the bowl levels are fine....half way on the sight classes....i have played with the position of the butterflies and nothing really happened.....checked the power valves and they are fine.....the Demon i have has the blow out proyection already installed...
so now i am back to square one.....the car runs good just really rich
but now it has a really bad miss.....so i guess i will yank all the plugs and clean them up.....i was thinking maybe something as simple as the gap on the plugs might be off....maybe i should open it up to allow more spark to burn the fuel.....or maybe even index the plugs.....i have jad mixed results in the past doing this though....the nitrous likes it....but stock motors just dont seem to run as well.....
any ideas are appretiated.
learned that the hard way once....well didnt learn anything....lol
yeah i did that with a small block i was firing up and cought a face full of fire...lol....and yeah the eyebrows and a little hair were gone....lol
i was looking to see if mt secondaries we pouring gas down the carb...it was and it ignited....i am a little more care full now...i use a mechanics mirror
