well one day after some adjustments i decided to take it for a ride and once in 3rd gear at wide open throttle there was an empty moment where i didnt hear anything...then all of a sudden i saw smoke out the exhaust and hear a rattling noise from under the hood......i was able to coast 3 miles before i had to park it and walk less than a 1/4 mile home.....once i got it home and took it apart i found this...
