    I need a replacement plug for my 99cc 4stroke predator clone and wondering if anyone knows what a good plug and gap for it would be?? The one in it now is an Autolite with the #s 275 on it. Thanks!!

    Howdy General.

    Not advise but I have never bothered to gap em. But there are many folks who are real experts. Did a quick search; https://www.google.com/search?q=htt...9i57j69i58.16310j0j4&sourceid=chrome&ie=UTF-8

    I like NGKs. If ya read a few of those, there is some great advise on ranges and what might work best for you.

    Personally, and gonna get yelled at for this, lol. But Have not found the super fantastic, high end plugs were any better than walmart or lawn dept. mid-range ones. (Wait for the admonishments!) But the racing folks and real pro builders are gonna be of far more help.

    That's just my experience and hope it helps.

    Some times ya can get a lil more life and a few starts just wire brushing and cleaning them.

    Was looking for a plug match-list and stumbled across this, General; https://www.briggsandstratton.com/n...g-the-spark-plug.html#CleaningFouledSparkPlug

    Kinda generic but good stuff. Also, the wires can go bad on ya. Those I prefer the uper end ones. Not crazy Expensive but good. And you can get em in any color and many styles. There is a ton of fancy ones with different styles of cover. Can really change the look of a MB with one.

    Dang, cant find any! Colored wires, plug caps. But sure some one will know of a good source. They do make a difference. I experimented with plugs yrs ago and found the wires made a much larger difference in performance.

    I really love that about these dumb things. Can experiment and fine tune for a few dollars.

    The plugs thing, folks swear the heat range is important. Living in CT. The temps in ridding weather are not real extreme.

    Just woke so rambling. LoL.

    Any pics, General?
