high emissions
last summer when i got my emissions tested and the motor was new for HC it tested 73 ppm @ 2500 and 150ppm @ idle. this time with about 10500 miles on the motor it tested 108ppm @ 2500 and 769ppm @ idle and i had to rev it up to 1300 for the idle test to get it to pass. what is wrong with it???????

HC is hydocarbons, which is usually excessive unburnt fuel. So your probably running a little rich.

i was going to take it back to the shop that did the motor for the adjustment but they want it for like a day and i don't want to let them have it that long so i am going to adjust it myself. how can i tell when the adjustment is just right for max power and low emissions? i'm running an edelbrock carb if it matters
