Hey guys i have a 2003 blaster i got it about 3 or 4 months ago. it worked fine for a few months untill one day i had ran it out of gas, and the next day i fill it up, pull the choke and go to start it and it revs up REALLY high! when i push the choke back in it kills it right then and there.... and will not start in the choke off position at all.... any ideas at all on what this may be??
