MarksA-C Posted March 23, 2009 Share Posted March 23, 2009 This is on a 16hp Briggs that I got to repalce the bad one in my 7016 (Needed a good block). What is it? Its like a spark plug spacer, moves it further way from the combustion chamber?? Quote Link to comment Share on other sites More sharing options...
msiebern Posted March 23, 2009 Share Posted March 23, 2009 Only a guess, but I would say someone stripped out the sparkplug hole and used this instead of a helicoil. Quote Link to comment Share on other sites More sharing options...
BLT Posted March 23, 2009 Share Posted March 23, 2009 Try this. Makes sense. http://ytforums.ytmag.com/ttforum/viewtopic.php?p=2169644&highlight=&sid=10ed75780713fb2dc6911e131a0570e6 Quote Link to comment Share on other sites More sharing options...
MPH Posted March 23, 2009 Share Posted March 23, 2009 Interesting read Bob, never heard of such a thing. Dang, got my 10 bucks worth again.^ Quote Link to comment Share on other sites More sharing options...
ka9bxg Posted March 23, 2009 Share Posted March 23, 2009 Those things work good. They are used for striped threads but they need to be deeper. I have a set on my standard twin tractor.A friend put them in when he worked on it. Don't know where to get them. Quote Link to comment Share on other sites More sharing options...
firefoxz1 Posted March 24, 2009 Share Posted March 24, 2009 I have seen these sold for cars for anti-fouling. If an engine burned oil you would install these to move the plug out of the combustion chamber to keep it from fouling up so quick. I have never seen one like this advertised to repair a plug hole but we all live to learn:) Quote Link to comment Share on other sites More sharing options...
acfarmer Posted March 24, 2009 Share Posted March 24, 2009 Its a spacer for an oil burning engine so the oil can't get to the tip of the plug and foul it. Quote Link to comment Share on other sites More sharing options...
JimH Posted March 24, 2009 Share Posted March 24, 2009 Old remedy from the past that works for anti fouling and stripped plug threads. Quote Link to comment Share on other sites More sharing options...
Zach Posted March 24, 2009 Share Posted March 24, 2009 So I guess its safe to assume that this engine burns oilB) Quote Link to comment Share on other sites More sharing options...
dentwizz Posted March 24, 2009 Share Posted March 24, 2009 Looks like a kinky way to use an automotive length plug too:p Quote Link to comment Share on other sites More sharing options...
joshuaareed Posted March 24, 2009 Share Posted March 24, 2009 Mark it is definitely an anti fouling unit. Quote Link to comment Share on other sites More sharing options...
perry Posted March 25, 2009 Share Posted March 25, 2009 yep, i have seen and have a few of them in heads. i have heard for a stripped head, just retap and use a larger plug from a wisconsin engine. Quote Link to comment Share on other sites More sharing options...

MrSteele Posted March 28, 2009 Share Posted March 28, 2009 Another thing we used to do on old car engines, tractors and such, as well, was to put a button inline at the end of the plug, and allow the spark to 'jump' across the space between the holes in the buttons. That kept a plug from fouling as quickly, and if you opened the hood and saw buttons, you knew there was a valve problem there. Quote Link to comment Share on other sites More sharing options...
