"I ran this motor at idle for
"I ran this motor at idle for about 10 seconds for the first time in three years. The next day I wanted to do a cold compression test but rather than spinning it dry, I thought I would squirt mixed gas in the carbs to lubricate the bearings before pulling the plugs. I have the motor off the boat and on a stand and only connected the starter. Well, it started and rapped out for as long as it took the fuel to burn and stopped (about 5 seconds). The plan was to squirt fuel in the intake and then spin it and squirt more while it was spinning, not to start it, that was loud, I think I woke the neighbors. I know better, I was just anxious and did not pull the plug wires.
My question is if you think I damaged anything by rapping it cold for that long? I think (I hope) there was a little lubrication left on the bearings from the brief start up the previous day but not sure.
Thanks, Kevin"
