Hey guys im new to this forum. i just bought a 1980 cb 750c. it wasnt running so i pulled the carbs and cleaned them and replaced the plugs. The bike ran but would not idle right. i adjusted the main idle srew and got it to idle but as soon as i would rev it up the idle would spike and stay at about 4000 rpm for awhile. also when i leave the gas on gas  flows out of the bottom of carb number one. dont know much about these older bikes so any help or suggestions i could get would be great!

thanks
