1) OMC specs QL77JC4, which I use in my '94 8HP 2 - stroke with good results. That is usually an easy plug to get around here, so no problem 90% of the time. 2) Occasionally I use NGK for availability or convenience. I go with the application spec from NGK themselves which for this motor is BR6HS In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70°C to 100°C from the combustion chamber. The heat range numbering system used by spark plug manufacturers is not universal. For example, a 10 heat range in Champion is not the same as a 10 heat range in NGK nor the same in Autolite With NGK spark plugs, the number in the middle of the part code designates the heat range so a B7ES has a heat range of 7 and a BP9ES a heat range of 9. A smaller number means a hotter plug (2 is the hottest) and conversely a higher number means a cooler plug (12 is the coolest) NOTE: Using NGK plugs is a good idea on more modern engines, however IF you have a scooter like this Razz that uses standard 14mm plugs, you would be better served to use Champion or Bosch. btw.. Champion has more spark plugs patents than any other company and they have licensed their tech to AC, NGK, Autolite, and some other
Reading spark plugs is an easy way to determine how an engine is running. Now, I'm going to cover the 3 most common conditions, lean, normal, and rich. Before I get into describing these common conditions, let's go over on how one would obtain such a reading through conducting a plug chop Worn Symptoms: Rounded electrodes with a small amount of deposits of the firing end. Normal colour. Causes hard starting in damp or cold weather and poor fuel economy. Recommendations: Plugs have been left in the engine too long. Replace with new plugs of the same heat range Look at the difference between an iridium-enhanced spark plug and a conventional copper plug. The iridium-enhanced center electrode is much smaller (.6 mm vs. 2.5 mm) to concentrate the spark. Plus, it holds a sharp edge longer

I agree the science is confusing especially when sorting thru auto, motorcycle and lawn equiptment plugs. The link to NGK's website is useful and helpful The single platinum spark plug is designed much like the copper spark plug but with a platinum disc welded to the tip of the center electrode. Platinum is more dense and durable than nickel alloy so it holds its sharp edge for more than 100 000 miles. Platinum spark plugs run higher temperatures which prevent deposit build-up which causes fouling In this case, plugs with the same heat range numbers can't be interchanged casually as being equal. To give an extreme case, NGK's BR2LM is equivalent to Champion's RJ19LM, which is a common spark plug for many lawnmowers. Reading spark plugs. The spark plug's firing end will be affected by the internal environment of the combustion chamber
