Wont start nc 30

[pete_vfr]

Well its another post from me i feel like ive rebuilt the bike and it still wont start, it turns over but doesnt fire like theres no fuel now up to date ive:
Replaced spark plugs
Stripped down and cleaned carbs
checked float valve heights and made sure they close and dont pass fuel
compression on the engine is good
checked ht leads and coil packs nice blue spark off each
fuel lines ive blown through no blockages

When shes running it sounds great nice and smooth, problem is i brought her to use on the track to give it ago but cant book a day now out of fear she wont start when i get there, so any other thoughts would be most helpful but i think after this atempt ill be looking for something else, cheers guys pete

have you checked the vacum hose isnt kinked or split? simple and you probably have already, but just a thought. start with the simple things first! :)

Cheers dude its had the fuel tap mod so the vacum pipe is disconected and capped off, theres fuel in the carbs and it must be sucking up into the chamber because if i just turn it over loads i end up with wet plugs

Remove the spark plugs and lay them on the engine, in the plug caps,and then crank the engine and check for spark.

Hi, maybe squirt a small drop of petrol down each carb inlet. and see if it'll fire up quick like that, if it doesnt run or even fire then it must be spark related.
Hope it helps
Cheers

Hey guys the spark plugs all spark fine off the engine case so yeah ill try putting some petrol down the carbs never no how much to put in though dont want to drown the plugs? i will give a try later today and let you know.cheers

If plugs are wet then there must be fuel in the chambers and a spark should ignite it. May be the plugs are too wet? How old are the plugs, do they still spark after you have wiped the fuel off them?

Hi all right tried starting the bike while sraying engine starter into the carb inlets and even then not even a hint of fireing up its very strange the plugs are new and when taken out they spark lovely and strong blue spark, where i go from here i dont know

[magg]

What if anything have you changed since the last time it ran? How long ago since it last ran?

Got the firing order the right way round?
