After trying so many different carb adjustments I looked into the hoses that connect to the carb, especially the vent tube that comes off the upper part of the carb that goes to the surge tank. I found that where I removed the carbon canister line that came off the bottom of the surge tank I had plugged that port. Well the canister vented to the atmosphere, so I removed the plug from the surge tank and now the engine starts without any problems or black smoke. I think I had essentially plugged the vent line that needs to be able to vent. This is a 2004 California roadie and there is not much information about how to remove the smog stuff. I hope that this can help out someone else who might have these sort of problems. I now have it set with the needle on the 4th groove no washer under the stock spacer,and PMS at 2.5. running great! I love my roadie now.
