I got a rickter fr2 with a 950 dasa. I running spark plufs br9es or br8es. Diff heat ratings have tried both. When my ski goes upside down i get some water in the carb throats. Then my spark plugs get wet and wont fire. But the wierd thing is. I take them out dry em and they still dont work. Have to put new plugs in. This happened about 4 times now. Then i leave the plugs for a few days to make sure they fully dry. try em again and they still dont work.
