Just wanted to throw this out there...68 cat with 74 windsor. has performer intake and 2 barrel carb...idles erratic....plugged all vacuum hoses...and set timing with a vacuum gauge as best i could...read somewhere to cover the carb with your hands and if the engine doesnt die then you have a leak so i thought id try...went to cover the carb and the girl revved up so quick i was in shock...i must have put my hand back and forth like what the!!!!....hmmm...put the BS air cleaner back on no change...took it off no change...cover with my hand revvs up high...smother it and the car dies....so my question is...is there something im missing being a newbee... do i need to find the original air cleaner cause maybe the air cleaner i have is letting too much air in..i was going to adjust the choke in the morning but my thinking is...it starts fine where its set and runs...I dont know...strange but seems so simple....any ideas or jokes for me?
