my nc 30 wont start. iv cleaned the plugs and it trys to start but just wont. iv tryed choke no choke slight choke. no fuel some fuel. all are sparking. i think its the batter, im gonna charge my batter and put a booster pack on to give it little extra kick

I would try new plugs, carb cleaner down the stacks, full choke no throttle, charged battery!! eh voila!!!

ill give that a go. ill tell you what happens! thanks

after taking carbs off and cleaning eventually getting back on my nc30 wouldn't start either i cleaned plugs and was sure it was fuel starvation so i put a temp fuel supply onto carbs with no tap started first time i looked at fuel tap and diaphragm
nothing obvious so put tank back on wouldn't start . when running vacuum hose gives a suck suck suck ect effect im about to take tank off again empty and re-examine diaphragm let you know what the result is later!

got mine started today for about 30 seconds.tuck plugs out then cleaned then then put in oven on 150 for about 10, then put back in bike with sone carb cleaner in to carbs. cof slutter and she sprung in to life sounded great for that 30 seconds. iv now got a problem.. i think the coils are BROKEN.. simple becouse we have spark then we dont. so ordering some colis next week to put on. ill update soon

it will be the plugs. Theya re very fragile and will die on you easily.

New plugs will have it sorted..it is the way!

Don't worry about the coils mate,like everyone else said new plugs will sort you.

dont know if this will help but u can meter coils ht lead to lead then input wires
mine was fuel tap so done hrc mod started first time it should be full choke no throttle :stu

Plugs go boom

sorry mate but it was the coild lol. she coft in to life wen i put new coils on woop!!!
