spark plug (ie) E3.32

Discussion in '2-Stroke Engines' started by WINDY CITY BOB, May 13, 2016.

  1. Hello Windy City Bob here. I have a two stroke Chinese generic motor. I installed the East 3.32 spark plug. I got about a quarter to a half mile from my house and heard a loud bang and it was my muffler that shot off of the pipe! SCARED THE CRAP OIT OF ME!!!LOL! I thought I had blown a hole in the side of my engine.
    So I picked it up stashed it in a bush and then as I found a bag I wrapped it up in a couple plastic bags and paper bags and strapped it to my rat with a couple bungee cords and made my way home. Man with this thing loud I mean very very loud. The plug is just about exactly the same size however I think that it may be too hot of a plug I'm told I am still a newbie here, So this is not my area of expertise.
    PLEASE contact me with any info THANX IN.ADVANCE. Bob.

    Might have just back fired but it would have been scary either way:D

    I have no clue what that spark plug is.
    The best I have found for a 2-stroke slant head like you have is the NGK 7544 (CR7HIX) Iridium plug and I use NGK Iridium's in everything I build, even 4-stroke builds.

    The 7 in the middle of the number is indeed the heat index number.
    The higher the number, the more heat it dissipates from the engine.


    If you live in the cold, go a lower number, here in the desert we go as high we can, 7's as standard, but even 8's on occasion.

    i had the same thing happen and i cant remember if i had the E3 plug or just a BikeBerry 3-prong plug. either way i think its just a coincidence, yes i could understand it (E3) being a tad too hot for the engine but i think its more luck of the draw with the mufflers on build quality......

    Run a good plug like a NGK B7HS or a B6HS. I get mine from the auto parts stores for about $2.50.

    NGK the smaller the number the hotter the plug it is just the opposite from Champion.
  7. Thanks a bunch. Especially for explaining how the heat works and the numbers that's an excellent excellent piece of information and thank you very much again
