From what I've read, jet sizes do vary from one model of carb to another, but despite this, the settings are always stated as 1 1/4 LOW, 1 3/8 HIGH.
Then we're told that there are manufacturing tolerances to bear in mind, so fine tuning is required in each installation.
When I replaced the stock 603 with an 813 on my FG MT G260RC, I needed to lean out and ended up with perhaps 1 1/16 LOW, 1 3/16 HIGH.

Stock is, or was 603.
They have been changing them a bit.
Check out Dave's, in the carburettor section. It states which are 'standard on x,y,z engine'.
