anyone had a problem like this?, my new scag with a 35hp briggs was only a few months old and the battery went dead. got a new one and noticed as it cranked over it seemed like now there was a dead spot in the starter. took it to the dealer and they put a new one in. called to make sure it was ready to pick up and they told me the had the engine apart and were now replacing the cam and it was not the starter?? it ran perfect once started, and would start fairly easy even with the "flat spot" while turing over so i was trying to think how or why a cam would be the issue. they said Briggs reccommended it so im assuming others have delt with this? i dealt with it all summer so not to take the mower out of service while it was being fixed, now im concerned some 18yo is tearing it apart and now something may not be done right which will be much more significant than a flatspot in a starter.
