Missing a beat
I have noticed on the odd occasion the engine misses a beat!
To be more specific, on odd occasions there is a momentary hesitation in the engine. The engine continues to run fine, and there are no subsequent problems. I know this isn’t type specific because I have had it happen on a number of different engine types, both injected and not. I think I also know that it doesn’t appear to be indicative of a problem with the engine. The miss a beat syndrome is pretty uncommon, maybe once every 100 hours, but of course it always gets ones attention.
I wonder how often other people notice this, and what is the likely cause. I guess it could be a momentary contamination of a plug, or maybe a little moisture in the fuel, but I have never really been certain.
Have others had this experience and what are the likely causes.
