Anyone ever experienced this? Just put new points (set to .020), coils, condensers, and plugs in my '54 Johnson 25 (RD-16), along with rebuilding the carb with new gaskets, valve/seat, and float and took her to the test tank. Thought I was good to go. She fired up in three pulls and I set the low speed (backed out 1.5 turns) and the high speed (.75 turns). After 5 minutes at idle, everything seemed ok, then, I turned the throttle to 'fast' to see if the high-revs were ok at idle. Well, it was good/normal for about 30 seconds, then, it just decided to just keep on revving. It was like it said to me, 'ok, buddy . . . hammer down!' I backed down the throttle - nothing. Turned high/low idle nobs to 0 - nothing. Tried to choke it out - nothing. Pulled the gas line waiting for it to just run itself out (hopefully b/f it blew a rod). I swear, I thought it was just going to blow up. What would cause a motor to just rev outta control? Until I know what happened, I'm afraid to use it - can't help but think if that were in gear and happened while approaching the dock.
