I second Brians advice -

My 40mm Dellortos used to spit and pop - I added the anti popping spacers from JAE and solved the problem -

They only hiss and pop now when the choke is on - or if the idle is too low -

The MORGAN CARB TUNE II is the only way to go to properly tune them in - not cheap at about $150 but well worth it -

It's also possible tht your main jets are worn out ? New ones are available but somewhat expensive -

Don't give up on them - once you've got them running right all will seem right with the world !! Nothing like running Dellotos on a 907 !
