Animal Jet Size

What is a good starting point on jet size for a stock walbro carb that is going to be running on alcohol on an animal?

From the jet kit use a 137 main and a 38 pilot put the needle in the richest position.
How about for purple or blue plate? I have a couple of unknown carbs and I'd like to take them apart and be able to identify what they were set up for.
Also....what other differences should I look for? Is the float height set the same?
Does anybody know what the jets should be if I am going to run pump gas instead of alcohol? It's set up for alcohol now.
Main jet is .95 mm
Idle / pilot jet is .32 mm
Nozzle is .103"
