So if there are no issues then just on every freshen up, ThanksI know a guy that replaces the spark plug at every rebuild weather it needs it or not.
Thats what caused us to toss them after 2 or 3 weekends.Replace it every few weekends. They last longer, but for $6, I don't want to find out where the line is with 3 to go in a feature that I'm leading.
If they truly don't manufacture the Autolite 3910X spark plugs, then they will have to rewrite rules for Briggs L206 engines as that is the spark plug specified for that crate race engine package.FYI they don't make the 3910x anymore autolite stopped making the X plugs i guess you can use them till there gone
if you go to their website you will not find it. they make a 'racing' plug called the 3910 but it has a conventional electrode and ground. upon calling them they say it is no longer manufactured. but Jody at ARC said he had a warehouse of them.If they truly don't manufacture the Autolite 3910X spark plugs, then they will have to rewrite rules for Briggs L206 engines as that is the spark plug specified for that crate race engine package.
Just before the recommended service interval. Manufacturers give suggested intervals based on best case scenario, which is why severe duty has quicker service intervals.how often do you all experience spark plug failure in your daily drivers? or your generators and lawn mowers? seems like you have bad luck in your racing engines.
