Tony, idi you come up with the idle holder number yet? There's a big chance you have to move up to 120 as Rick says. As it look you have a rich low-end it might also be a acc-pump setting, although I've not done any work on the IDA's I'll have to loook it up in a book!

Your mains and airs look OK (although they might not be ideal for your setup- testing & measuring will tell).

The puffing & popping might not be caused by fuel. The carb sync need to be 100% spot on; always... The tendency for nuts & bolts in the links to move slightly made me move away from the webers in racing applic.

Get the timing up as adviced as well.

It will run good in the end, so spend your time fiddling with those carbs.
