More CB750 fun

So, gentlemen, the story so far is that my CB750 carbs were blocked. I took them off and cleaned out the jets - three jets per carb.

Still doesn't work. It runs fine on easystart - if I keep spraying it runs continuously.

Did I miss something in the carbs? What else could it be? I guess easystart is a lot easier to ignite and maybe a very weak spark will let it run on easystart but not petrol? Is this likely or should I be looking at the carbs again?

Cheers,

Nick
