RE: IML: 69 Won't pass emmissions

John:
Great to hear that you got your car to pass. I would still look into
increasing the primary metering rods one size to improve your fuel
economy and reduce emmissions. Just for comparison, my '58 392 passed at
1.02% CO and 98 ppm HC on a well worn engine with the original carb
leaned out 1 step from stock.

I put on a Carter 9636 that I got from Jegs Performance. I finally got
it to 
pass. I went in a different line this time. The tester told me " one
more 
time through & they would need to put me on the payroll".
    The HC standard under load is 450 & it passed at 197. Idle standard
450, 
passed at 256.
     The Co test under load is the one I was having trouble passing. The

standard 3.75 & finally passed at 3.69. Co idle standard 5.00 passed at
.46.
