Did you have to replace the main nozzle? I had mixed results getting them to seal on 562 carbs
Make sure to do the tank vent gutting the Mastermind way...

Vent is modded, the new main nozzle sealed and held in testing.

I haven't done any nozzle changes on 572 carbs yet... They look very similar though.
What was used to seal the nozzle in place?
The 562 ones I've worked on seemed to be installed dry from Zama.
Has anyone fitted a 572 carb on a 562 yet?

They appear to be slightly oversized and are driven in dry.

Well, I kinda find this a little odd.

So you brought saw in for running rich?

Yeah, had a rich bog from when it popped.

Happened to me on one of the original 562’s. It sounded rich, but it was a lean bog and the computer was instantly trying to compensate which ended up bogging it rich. Try it with stock ignition timing

I dont think its an ignition timing issue, but I'll try it.

Its still messed up. Im about done with messing with it.

Pig rich

I spoke to the dealer i buy from, he was shocked it had issues with 21 hours on it, and is replacing the carb and any other issues. I am so grateful.

I’d look at the plug color. Upper end oils can give you spooge

Jeeesh. Sorry to hear of all these issues with your 572 Dominick.
Mason has had real good luck with his 572.

Nothing wrong with either of those. That's a good mix.
