SPARK PLUG ISUUES WITH ONAN GENERATOR

[CAUTION GONNA FLY]

I have a 4.0 bfa gen set. On my trip this weekend it started running very bad,shaking and just sounding bad. I pulled the spark plug and it was worn down to a point ''like a needle'' on the center electrode .I replaced it and it ran fine. My quetsion is what would cause it wear down like that???

It might just be normal wear, read this.

I also use Lucs Oil fuel treatment in my vehicles. Do you think this could have caused this???? I have never had any problems in my other vehicles.

Joe,it has 2200 hours on it. The oil and filter were changed 40 hours ago. I have never let the fuel in my tank get low. It has been started with the a/c in the on position a few days ago..will not happen again!!! The unit is in a well taken care of 85 Mallard on a Chevy chassis.28 ft . The engine is a 350 and loves the gas station even after a tune up..I drive 55 now...also camp 10 miles from home lol .Thanks for the feedback. Jerry

I think Richard might be right in saying "normal wear". It is recommended to change the plugs every 500 hours.
