The car has been parked for the winter since September. Motor is an olds 350 with hei petronix distributor. During the winter I changed the distributor cap, rotor, ignition modual, and spark plugs. Went to start it last week and can't get it going. If I flip the choke on the carb closed it'll start but wont stay running without staying on the gas. It also has lots of white smoke coming out the exhaust when this happens. Once I turn the car off after the initial start it wont start again no matter what. I can turn the choke on or off and no difference. It does seem to backfire sometimes only with the choke off. Any ideas on what I screwed up. Did I possibly mess the timing up when changing cap and rotor? Thanks in advance for the help.
