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?
