you'll have to break out a meter and start checking things. could be a starter switch, starter relay or just needed a starter rebuild. also if your bike has safety switches like brake handles, clutch and nuetral switches check all them.

Ricky, here is a link to the history of the Remington 742:

This paragraph has the most pertinent information:

"The Model 742 serial number sequence was changed on November 26, 1968 as a result of the 1968 Gun Control Act that required no two guns from the same manufacturer have the same serial number. The initial Model 742 serial number sequence began at 1001 and ended at 396562. The new serial number sequence, now shared with the Model 760 pump-action rifle, began at 6900000"

serial for what? Motor, Brand. Boat?

Your Winchester 290 was made between 1968 and 1973.
