Fuel on plugs
Well I've got a fresh built motor in the car and I'm just about done getting the exhaust repaired so I can hear whats going on. I'd like to start tuning. I've managed to get the car to idle and timed in at 6 deg. Idles around 800 not to erratic, pretty steady. But it smells extremley rich. Granted open headers and all but still pretty rich. So I got bored and decided to pull a couple of plugs to get an idea of how it's running without a real tune on it. Now I've only had this motor running long enough to get the timing set maybe 10 min total. The top of the plug and a couple of threads was pure black and at the tip it was wet, but not oil. Pure gas on the plugs. So i'm curious how can I get this from happening, drop the pressure maybe? I also checked the how much vacuum the motor is getting at idle shows about 13.5 in/hg, is that low for the cam I have? Or about right. I'm afraid of washing out the cylinder walls while trying to tune it, I can't afford to rebuild this thing again so I really need to stop it from running so rich while I check for any leaks and figure out how to tune it. Any help would be appreciated.

Re: Fuel on plugs
I would say check your fuel pressure and make sure your jets are working correctly.

Don't mean jets, was trying to say injectors.
Sorry, for the misspelling. Watching the Packers and Vikes play MNF.
