84 GMC...350...Holly fuel pump, Edlebrock carburator...notice the last couple starts...short burst of white smoke with rich gas smell at startup...other than that...engine started and ran fine...I have noticed it runs very high at idle like choke is stuck when first started up...have to punch gas and it idles back down...figured that was because of cold weahter...out of blue...start it last night...an extreme amount of white smoke coming out of exhaust and almost smells like gas itself...engine cut off...tried starting again...turned key and heard thump sound under hood...almost like starter wasn't working...engine wouldn't turn at all....then was able to get engine to turn over by doing nothing at all...just waiting a minute or two and trying again...but white smoke still pouring out of exhaust and hearing very loud knocking noise in motor and won't stay running unless you constantly give it gas....all the while...white smoke with extreme gas smell pouring out...
Help ! Any suggestions on where to start?
