tankdriver Posted January 12, 2016 Share Posted January 12, 2016 Check it out ....... As shown in the TM9-834... Only thing I can say is, Thank You, to my new best friend.. G503 member Frenchman....... Couple things missing, If anybody has them PLEASE let me know...... Can of abrasise 6 plug adapters 3 gap tools Battery clips Manual for it..... Thanks Again Frenchman..... Quote Link to comment Share on other sites More sharing options...
fv1609 Posted January 12, 2016 Share Posted January 12, 2016 Abrasive grit http://www.ebay.co.uk/itm/SPARK-PLUG-CLEANER-ABRASIVE-GRIT-1-PACK-/161153658127?hash=item258581ad0f:g:tEYAAOxypNtSie5c But there are lots of US sellers that would be better for you. Looks a fun machine, I have a more basic cleaner & it is jolly good at getting carbon off the insulator. If the plug is oily degrease it first. Only use it for just long enough to get the deposits off to avoid damaging the glaze on the porcelain. I once thought that a plug that has been blasted, looks & behaves as good as new. But this is not the case, it will perform worse than a plug that has just been brushed, filed & adjusted. In that it will need a higher voltage to get a spark. The problem is that the blasting rounds the electrodes & this makes it more difficult for a spark to jump the gap, so a higher voltage is needed. So what I do is after blasting, sharpen up the electrodes with a plug file & gap them, followed by a good blast of air to dislodge flings & any grit. The least voltage required to jump the gap is of course a brand new plug. Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted January 12, 2016 Share Posted January 12, 2016 Where I first started work, we had a Champion cleaner and tester. Used to test new plugs before going out on a job, and it was not unusual to have one fail or falter as you increased the simulated cylinder pressure. So a very useful tool.

The 2 holes up front is for testing. You put a new in 1 hole and the one you just cleaned in the second hole set the air which acts like compression, and compare the spark in the mirror..... Pretty neat..... Quote Link to comment Share on other sites More sharing options...
fv1609 Posted January 12, 2016 Share Posted January 12, 2016 Yes that's super being able to test under compression. I wish I could find an easy way to simulate such a test. Often people see a spark at the plug & assume that it be able to produce a spark in the engine. But that will depend on the plug & what the coil can deliver. Also determined by the engine's compression ratio, although its not just the pressure alone it is the gas density which of course depends on mixture. I can't see an easy or safe way of simulating that! Quote Link to comment Share on other sites More sharing options...
