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?

Thanks

You can fool some of the people some of the time
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.
