Gonna sit by the fire and think a while
I had a similar thing on the 413 in my '62. I thought the rids were going as it really knocked at start up and shut down. Turned out to be a shot harmonic balancer! Discovered this when trying to time the motor and the mark kept moving.Well, i got the pump on... squirted a little gas down the carb and it fired up... took a couple times, and some rough running for a bit, but then it smoothed out and ran ok...
i am not too happy as there is a light "knock" or tapping noise coming from the front of the motor it seems ugh
