I have a GSXR 600 that I've put in a dwarf car. I don't know to much about motors so forgive this question if it is stupid. When I started the motor today the idle was low and it started to stall, when I tried to give it some gas it stalled, with a strong smell of fuel. I took the plugs out and they were wet and very dirty. After cleaning them with a wire brush I put them back in and the motor still would not start. I'm going to get new plugs, should this fix my problem or is there a bigger problem with the motor. The motor ran fine before this happened.
