my mk blade not starting

hi everyone

took the car out yesterday to work (2 miles) running outside for 20 mins then just cuts out and refuses to start.had to get it recovered back home again.

this is what ive checked so far ..

took the plugs out as i could smell petrol poss flooded. plugs soaking wet !!

they were new plugs about one hours use. cranked the engine over to clear out the petrol from cylinders ,and ive got a lot of petrol just being pumped out of either number 2 or 3 cylinder cant remember which one (like cap fulls not a fine mist like the other cylinders.

i thought i sorted this problem by fitting a dyno jet kit ive now fitted six sets of new plugs cover four miles and started the engine prop 20 times always start to misfire runs rough number 2 or 3 cyliner poping backfiring .

tonite stripped the carbs down again took the floot bowls of removed the plastic floats checked the valves all look ok cant see any dirt anywhere.

running a fireblade pump and dyno jet kit from andy at ab performance

im just stuck now not sure what to check next ??????

p.s there is a spark on each spark plug

cheers simon sorry its long winded

It certainly sound like float valves not sealing properly.
I think it's safe to say it's not the plugs! Can I have one of your "old" sets?
The Blade engine is sensitive to wetted plugs, and once soaked they need to come out and be dried properly (with a blowtorch?) once dry they'll be fine again
