Hi everyone , just bought a new 150cc quantum , I bought it Wednesday rode it home 4 miles and changed the motor oil to castrol syntec ,rode it for another 80 miles rode great , the next day I changed the engine oil and trans gear oil plus added prima magnetic drain plugs , also bought an Ngk iridium plug went to instal it , well the Chinese plug turned a few times and stopped? Didn't try any further in fear of damaging head si I re tightened it put cap back on and it won't start ? So I took cap back off put in the iridium plug (not in head cap only ) to check spark against scooter frame , it was a strong blue spark , did I damage plug? Also I noticed a vacuum line that was not attached to anything just a wide open line , perhaps it's this? Should I force the plug a little more ? I think it is seized or cross threaded , please help Thanks

Back the plug out till it stops again and put a drop or two of oil on the threads and run it back in and out again till you get it out

That's a bad feeling, with the soak plug I agree with cyborg.

could have been crossthreaded at the factory,,,when you do finally get it out,,inspect the threads in the head really well ,, hopefully the head is not bad,,altho inserts work well and are easy to do and are very inexpensive,,,and use a few light drops of copper anti seize on the new plug threads,,,,

If it is stripped and won't thread out You need to get vise grip pliers grab the plug and pull as you turn it counter clockwise to unscrew it out.
