Owner reviews for spark plug

11500tfc. Propane. Torch plug replaced w NGK BP7ES. Trouble free thus far thru 2 outages of 125+~ hours.

I have the 11500TFC, its been great no problems. Just change the spark plug to NGK.

like NGK for plugs and wires on my car.

Toyota sounds like great deal if they actually use OEM plug (DENSO iridium). That part alone is \\~$18 each (you need 6).

Buy the spark plugs, NGK brand, off of RockAuto.

Yes. However as a long time old car mechanic I learned the hard way some new cars are super picky about what spark plugs you put in them. It kind of caught me by surprise. Parts store gave me Bosch plugs their system matched to my GF's Pilot, and it fell on its face hard about a half hour into the next drive.

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

Problem solved: I got a internally bad ac delco spark plug. Gap and everything was correct no cracks I could see literally just a bad plug.

I highly recommend avoiding anything other than exactly what is specified in your owners manual, I currently have bad gas mileage because I was too curious to see if the desno two tip would do as good as the other stuff.
