Why does my 1990 scottsdale with a 355 ci. - Smell like its running rich all the time? i was told to advance the timing 4 degrees because at 0 it would run backwards. so when i advanced it 4 degrees it stopped but now when im at a stop and hit the accelerator hard it stalls then picks up after about a sec. it bugs me because i just rebuilt it all and have well over $2000 in it. please help me!!

backwards?? i dont think so.

it all depends on the cam you have, weights in the distributor and whether you have a vacuum advance.

what kind of carb are you using??
