Spark plug NGK or OEM Mazda

yup those are done.

the center electode is worn flat and the gap is way too wide.

just replace them. make sure yu use the specified NGK or Denso Iridium plugs.

Yes, they have a lot of buildup and deposits. Make sure you get that exact spark plug again same brand everything don't put anything other than the NGK that originally came with

Fairly easy to do,ive seen this plugs go past 150k honda tech here.

Factory plugs were causing the auto transmision to take longer to shift and jerk more suprisingly. I assume because the engine was acting differently than the transmission expected.

Make sure you get NGKs: FA/FB/EJ/Etc. love those the most.

Also you might have bad type of plugs - NGK PFR6T-10G is correct one.

Yes, all the time. No big deal!

The CX5 should not be a problem. All the posts telling horror stories aren’t answering the question. You don’t need to be ripped-off by a dealer for this task. You must have a Friend or neighbor to help! It’s a 30 min job at the most. Be sure to get the right plugs, NGK is a great brand.

i got a cheap 80cc kit a while ago and it ran awesome for about 3 months, then i let it sit for almost a year in a garage. Now rusted in some places, but still spins freely, and piston is intact. I just installed a centrifugal clutch and a pull starter, along with a new cdi and new coil, but it just wont start no matter what. I keep pulling and pulling and nothing. I even got a lower temp spark plug for it (NGK B7HS). Fuel is going in, carb seems to be working, i believe im using good enough fuel, tried many different fuel/air mixes... but nothing. Can anyone here please help me figure out what could be wrong? If you need any additional info please ask.

EDIT: after some back and forth with the comments, i decided ill try and disassemble/clean the carburetor, and maybe some other things suggested.

I also realize my formatting isnt the best, but this was one of the first few times i posted in reddit, ever...

And to address me just chucking in new parts suddenly? yeah, not the best move, i realize, but ill try and make it work, and a lesson learned.

Anyway, thank you for the help everyone! I very much appreciate it. Perhaps ill post an update on whether i managed to get it running or not

UPDATE: Today i tried most of what you all suggested and unfortunately, still nothing. I opened the carburetor, as clean as could be.

At this point, my only two suspecrs left is the crankshaft magnet getting misaligned, or im just not getting enough rpm with the pull starter, which is already kind of bogus because it produced a decent spark even when not pulling too fast

I just got some fakes with the EAC logo on the box and the accurate Japan stamp with the line under the p. I could tell they were fake just by looking at the poorly machined threads, let alone the crooked ground electrode that looks like it is made out of casted tin lol.

I bought 2 sets of NGK Irridium plugs from Amazon sellers that turned out to be counterfeit. The electrodes were completely worn off with 60k miles on them. They are supposed to last 100,000 miles. The cars were misfiring and had spark knock.
