Hey whatsup .....haven't been on here fer awhile. I just been down to get my '74 CB750 up and running after cleaning out the tank and carbs REAL GOOD.Even put on new fuel lines, clean petcock. And it's like this...I pulled out the choke and she started right up. She was revving pretty sweet but wouldn't idle then slowly lost power.Turned OUT the idle screws a 1/2 turn checked the plugs and they were all carbon fouled. Got my plug file and cleaned them up.Tried again and she was revving but for a shorter amount of time and then stalled. Another half turn of the idle screws, cleaned each plug again and the same shit happened again. Any suggestions-shit, any shops that will take a '74 CB750? I'm fuckin' fed up...<img src=icon_smile_tongue.gif border=0 align=middle>

Hey yes they are black and sooty, the plugs and the exhaust too. So I've had the bike since April, it came from Georgia. She was running fine with absolutely no problems, she came with 4 into 1 pipes and uni filters. Then about a month and a half after she started idling worse and worse and started backfiring a bit. Changed the plugs to fresh ones from NGK D8EA to NGK D8ES and still the same problem. Cleaned my tank, petcock, put new fuel lines on, and then pulled the carbs which were really clean to begin with. Installed a fresh set of pod filters. I've been told that I could be running too rich through the carbs but the idle screws dont seem to help much with this. Hey do think there's any chance that it needs to be rejetted because of her new home from GA to NY?

Cheers
