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.

Pros: easy to do, cheap
Cons: expedited wear
Vehicle: Mazda 3
Mileage: 60000 km

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.

Pros: NGK is a great brand
Cons: 30 min job at most
Vehicle: Mazda

I’d personally run NGK, they have always performed better than Bosch in these generation engines. Iridium if possible and just whatever my reputable local parts supplier would get me.

Pros: better performance

I'll just start with my bias of never using Denso for anything anymore but for plugs I only use NGK laser iridium and always get at least 80k out of them.

Pros: 80k out of them
Cons: never using Denso
Mileage: 80000 km

NGK Spark plug

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

Pros: ran awesome, spins freely
Cons: won't start, rusted in places

Ngks are fine but be careful with them. I myself ran these and changed them at 10k intervals. I met someone at a car meet who recommended 5k intervals w these n I didn’t understand till my engine was gone. They can foul up and break inside the cylinder. Granted in my case it was my fault but it’s happened a few times w other ppl.

Pros: fine performance
Cons: can foul up, break inside cylinder
Mileage: 10000 km

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.

Pros: accurate Japan stamp
Cons: poorly machined threads
