Buy the special screwdriver for the security screws. Unplug the machine. Wrap yourself in aluminium foil to protect you from microwaves. Find the sounder on the main board and fill it with epoxy resin. Don't touch the big capacitor looking thing as it stores 600 volts, just waiting to zap you, heart stoppingly so. Don't breathe too deeply as the magnetron core contains poisonous heavy metals. Now you know why it has security screws!
I have a few tips about spark plugs you might find helpful, alongside watching some youtube videos
1. did you know you can use a multi-meter to test and see the continuity is correct. (more helpful when making sure all 4 or 6 plugs are offering the same spark)
2. as for the spark-plug designs,. the shorter the Ceramic end the hotter the plug gets. so sometimes you can affect overheating by lengthening the plug length, or vice versa.
3. the GAP you can just google the spark-plug number and put the word GAP. it will give you the gap manufacturers recommends .
4. you can also adjust spark by shortening the gap, to make it fire faster, with less spark, or make GAP bigger to increase the spark length and make it longer. (in the olden days, they used to make some fine tuning in these areas)
i.e. most people now don't know much about spark-plugs so they just use the factory default, when a manual is telling you to use a certain spark-plug Manufacturers Number, they also mean for you to use the GAP that is factory Set.
5 it is good to measure the GAP on all plugs even brand new, since they can change from being tapped by accident in shipping.
6. the gap is measured with a tool that has approx. 6 different thickness wires, or spacers, and some kind of small bending device, for you to make adjustments to the upper lever arm on the spark pin.
the GAP on all spark plugs, share a range of approx.6mm .
as I mentioned the length of ceramics, affects heat more than GAP.
So in most cases it is best to use recommended spark plug, BECAUSE THE LENGTH OF THE END GOING INTO CHAMBER NEEDS TO NOT HIT THE BOTTOM OF THE PLUG WITH PISTON

all the things I said should give you an idea of what I know, please watch youtube videos, alongside with my advice for reference, be careful with spark-plugs to always HAND TIGHTEN. and not STRIP THE THREAD ON THE ENGINE. especially with cheep china motors.
quick tip. if you have a head that can bolt on any direction with a slant plug., turn plug angle away from intake port. and towards exhaust port. . if you want more power. port the cylinder intake(pitted to cause fuel to get spread) and the exhaust smooth, and made larger. have fun, & always good to be practicing these port adjustments to a spare cylinder if they only cost $40.
NEVER USE SANDPAPER TO CLEAN AND REUSE PLUGS.
UNLESS YOU CAN BLOW THEM OUT TOTALLY WITH HIGH AIR PRESSURE. since any sand from the paper that gets into you cylinder will cause minor and small long term damage. THINK AHEAD ALWAYS GOOD TO BUY A NEW PLUG FOR $3 over RECYCLED
oh and I don't ever waste money on d'em expensive plugs replacements, they all do the exact same thing, the multi-meter test I marked is more important, reason to take one over the other, the different power is not achieved by quality. a regular champion copper plug is always good for me. and if it fails I replace them.
the difference between the 2 cycle plugs and 4,6,8 cylinder plugscrapis more about cutting engine noise with the stuff inside the upper-mid part of the ceramic housing.
*unless you own a TOYOTA .DENZO OEM PLUGS ARE 10 year plugs but 10x the price. I recommend DENZO only for TOYOTA
all the other plugs are the same ****, designed to fire at the same exact temps, and spark and everything. that is how they are all interchangeable, and your car doesn't go faster from changing between brands, they are all designed to fit within exact manufacturers specs. so don't get excited with the special packaging or shapes. or metals they will claim to use... to achieve the exact same numbers as the cheaper version they make themselves. quite funny to see , once you get to the spark plug isle and see the COLORFUL selection
last tip on spark plugs, never put them near your wind shield. they can break glass with a little drop from a few inches away.

Spark plug gap should be: 0.020" and the fuel to oil ratio is 40:1. Be sure to use fresh fuel and a modern synthetic saw oil available at home centers, hardware stores, and saw dealers. Mix well in it's own container and be sure to shake the container thoroughly each time just before filling the tank to prevent oil starvation. Hope this helps!
Tilt it over so the oil cap is on the bottom...it'll rest on the handle and hang there...put a container under the oil fill pipe...something shallow like a glad sandwich container works perfect...get a paper towel, and reach under an unscrew the cap...all the oil runs out into the container...it'll fit !!
Wipe the dipstick off clean, and put it aside...take this time to look at your blade on the other side...it "should look" similar to wood chisel at the last 5 inches of the blade on both ends followed by a wing under it...BTW: their $12 bucks new...and worth it !!
Go back and look at the container and be sure the oil is finished draining...take the lid for the container and snap it on and move it out of the way (no body likes an oil spill)...wipe off the oil fill spout, and re-fill...takes about a half a quart, so don't over fill it !!!
I have no idea about how to install the actual device but I have read and tried mounting equipment out of doors and have these suggestions. I would get a rubberized food storage container that the item will fit into and a lid would close on it without problems. No gaps in the lid. I would cut only the holes I need for the connections to the item, put the item in the food storage container and take silicone caulk to seal around the holes used for the wires to connect to the item. If you had to cut a bigger hole for a large connector on a cable, use household window screen to fill in the hole around the cable and then use the silicone to coat and attach the screen to the food storage container
I will check, meanwhile go to the hardware store and get a replacement plug for it. the cord has a ribbed conductor and a smooth conductor. the ribbed conductor goes on the brass screw on the replacement plug. the smooth one goes on the other.
