Both are resistive type plugs. The "R" indicates a resistor plug and the "Q" a EMS (electromagnetic suppression) resistor plug used to reduce noise in sensitive digital electronic circuits. In automotive uses Champion lists some Saab's requiring this "Q" plug.
Lawn and garden small engines substituting to the RC12YC plug works just fine. In fact Sears will send you the RC12YC as a OEM part even though the engine was shipped with QC12YC plugs.
I found lots of replacements for the Champion rc12yc but none for the yx. Are they the same spark plug? Why wouldn't anyone carry a spark plug for a lawn mower that's two years old?
Not really, but that is the only plug Sears sells as a substitute. The RC12YC plug looks like it was designed for a gap of 0.035-0.040", while the RC12YX plug was clearly designed for the recommended 0.020" gap. The RC12YC electrode is a fat cylinder like most spark plugs, while the electrode of the RC12YX is cut down to about half of the diameter. I'd guess the special RC12YX makes it easier to start the engine on a single pull.
Champion RA8HC has the same thread, seat, reach, hex size, and terminal type. I ordered a Kohler plug from Amazon and they actually shipped me this Champion Plug.
I was wondering the same thing this afternoon
rc is a taller electrode plug physically so im stumped ?? and has taller and different center electrode than "QC" may interfere combustion cycles. maybe not enough tech data on these forums
The spark plug locations are all on the same side of the engine. They are in the side of the head, where the plug wires are connected.
They are all the exact same, all serving the same function. The different lengths are solely for convenience.
No there are a number of different types of spark plug.
You pull the ruber boot off the top of the spark plug , take the plug out, put boot back on the plug, touch steel part of the plug to steel on motor,pull motor over while watching the gap on the plug if you see spark it should be ok if no spark do the same with a spark plug you know is good to make sure it is the plug. Hope this helps
ngk Bm6a its the same plug
They're almost the same plug - according to NGK's spark plug guide the S has a standard 2.5mm electrode and the A is a 'special design' - no more info given than that!
It appears to be NGK r6918b-8. Doing a little searching I found the spark plug above listed as: "NGK special spark plug for (1996-2000) RM 125." This same spark plug is listed in the 2003 RM 125 Service Manual as the correct spark plug for that engine.
That is the gasket. XXXXXXXXXXXXXXXXXXX A gasket or washer is NOT required on a tapered seat spark plug.
You can check for spark by removing the plug wire from the spark plug and holding it about 1/4 inch from ground. Have some one crank the engine or pull the starter rope and look for a spark to jump from the spark plug wire to ground. DO NOT hold the wire with your bare hands since you will get shocked. If you have spark there, remove the spark plug and insert it into the end of the spark plug wire and do the same procedure. If there is no spark, the plug is bad. If you have spark, the problem lies elsewhwere.
Disconnect the battery, and remove the spark plug wires one by one. Replace the spark plug wires in the same order, ensure the connection is firm, and connect the battery.
A 2005 Honda Element should have a spark plug gap that is set at .044 inches. Almost all Honda engines are set with the same spark plug gap.
Yes... Where all the spark plug wires go into the same spot.Yes... Where all the spark plug wires go into the same spot.
take the spark plug out of the head. then put the spark plug wire back on the spark plug. ground the plug on the engine you can do this by putting the plug any where there is metal and lay it on it. then turn engine over and see if you have spark. if not then do the same thing with just the wire by putting a Philips screw driver in place of the plug, ground it turn over the engine see if there is a spark if their is the plug is bad. if not then the coil or flywheel is bad more than likely it is the coil
Pull the spark plug wires off the spark plugs. Remove the spark plugs with a spark plug socket. Install the new spark plugs and put the spark plug wires back on. I recomend replacing the spark plug wires as well. If replacing them, just remember that the new wires are hooked up the same ways that the old ones came off.
do they use the same plugs
same as any other car u remove the spark lead from the top of the engine beside the rocker cover then use a spark plug socket (which is longer than a normal one) to remove each spark plug be careful to put the leads back onto the same spark plug you removed and not to over tighten the spark plugs.
no, it takes the same socket as the others. most likely something is down in the hole next to the spark plug
