i had the same troubles, but it was with my first tank of gas... the gas from the dealer, was a bad tank it had water in it... and the water was clogging up my carb..... what i did to get my Z back to the truck was once i got it to start, i had the air filter off and covered the intake with a rag and gave it some gas and it forced the water off of the jets so gas could get through.. once i got it home i cleaned the carb and drain the tank and put fresh gas in a it's ran fine ever since..
