I made another thread a while ago asking for solutions on a no-spark (never ran) on my first (and to date only) build using the following kit from Amazon, which can be found here - it focused on the electrical connections.
I'm getting rather exasperated with this bike and it's general refusal to run, and am trying to acquire a new spark plug. Should I contact the manufacturer to obtain a new plug under the warranty, or are they easy to find?

I've included a picture to help identify. There's no other information written on the plug besides the "E6TC" visible in the picture.

it’s probably not the plug. A fouled plug is not a worn plug.

Ya cut the guy a little slack Tony. He is 17 and not dry behind the ears.

Brass Mann. a very cheap fix may be replacing the CDI. My neighbor bought a Two Stink bike and very shortly it refused to run. Chris came down with a long face to tell me about it. He got a new CDI and has been running great ever since. Try it.

Should I get this CDI from a specific supplier or contact the manufacturer to receive an identical one under warranty?

CDH power has a decent set or you can wait for the DLH best of the best to come back in stock...

Reading the plug will get you to the proper plug... I sudgest a 6 but if you're in summer a 7 in ngk is a little colder the oil ratio and how rich or lean the air fuel ratio is and how you ride can effect it if you're putting around or full throttle effects it also.. the point is use the posts on here as a guide but it's going to be your specific engine and these other factors that will help you dial in the plug and jets that your eventually going to find work best... If you start out rich and cold you won't damage your engine and as it breaks in they will lean out a bit as it's making more power after the first few gallons...

Spark Plugs that cross over to the 66/80cc happy time motors...
Accel - 0453
AC Delco - R44F
Autolite - 4123, 425, 275, 4093, XS4093
Beru - 14R-7BU
Bosch - W6AC WR6BC+, WR7BC+
Champion - L82YC, RL82YC, L86C
Daytona Maxfire - 61490

Eyquem - 775SX
Motorcraft - AER32

SplitFire - SF265F, SF412C <--- both discontinued - Shucks!!
Torch - E6TC, E6RTC

Also, for those of you who are looking for a "shorty" plug for a tight fitting engine, I managed to find some 3/8" reach plugs that will fit just fine in the stock heads that came with 1/2" reach plugs.

Autolite - 2974, XST2974, 254, XST254 ( The 254 has a solid terminal bud that won't work with the stock cap, if this is a problem, use the 2974 which has a threaded terminal bud. )
NGK - BM7
