And there it is.
It’s not really about making it run better....... you just want some new bling for the motor.
Nothing wrong with that....... it’s part of the hobby.
I think after all this waffling....... you owe it to the forum to order those things up.
As for new/different carbs maybe/maybe not running better........
New doesn’t necessarily equal “good”.
New is “unknown”.......... might be good...... might not.
I can tell you I’ve tested plenty of new carbs that didn’t work all that well.
