ok so i recently bought a 2003 arctic cat 400 4x4. i bought it cheap cause it didn't have spark, so i found the magnents fell off flywheel. i J.B. welded them back on and bike runs. i had one clogged jet. i took the fuel shut off valve out off tank to clean valve plus tank and found two small filters on valve were basically disintigrated. do i need to replace or could i put a inline filter in. the fuel was running out the overflow before and i didn't know if it was getting to much fuel since the filters were torn and opened up.
