GK73 Tick over

I have had this bike a while now and have never been able to get the thing to tick over properly! I have rebuilt the carbs using new o-rings, cleaned the jets etc but it just wont tick over. It revs right through cleanly now (was stalling at about 8k before). I have set the carbs to 1.5 turns out which i think is correct?
Have also tried adjusting the tick over but it goes from not ticking over to ticking over at about 3-4k! Anyone got any suggestions as to what i could try next?
Thanks

Hey,
My 73 would never tick over unless the mixture screws were 2x turn`s out but every set of carbs are different(wear etc),have you balanced them buddy?

yes ive balanced them and she runs and revs perfectly it just will not tick over which is very annoying when you come to a set of traffic lights lol. Sometimes it sits at 3k for a while before it cuts out which made me think it was the jets but they are clear as day.
hmmm a mystery thanks for your help though

Hi,
Had a similar problem last year. I rebuilt a damaged engine and renewed the o-rings, set the mixture screws and started the bike. It ran at high revs then settled for a while. after about 5 minutes the bike stopped idling, fouled number 4 plug and died. I reset the float heights to 14.5mm and balanced the carbs and the bike has run perfectly since. Worth a try. If you've got fuel, air and a spark and the bike starts and runs (however poorly)theres only a few things within each system it could be really.
Hopefully this helps

Thanks for the suggestion. How would i alter the float height? what specific point does it need to be measured from? Didnt think about this when i was rebuilding the carbs so hopefully this could be a help!
thanks
