I just wanted to ask and make sure I'm right about a carb. I'm fixing to rebuild a Marvel Schebler TSX-361A. Where the economizer jet is in the Marvel 241 carbs, in the 361A and 458 carbs it is a dead hole correct? The hole is cast into the body but it doesn't go anywhere like it does on the 241 carbs. At least that's what I was thinking. The one I'm fixing to rebuild is very,very rusty so I will probably use my trusty old bucket of toilet bowl cleaner but I wanted to make sure that there isn't an orifice in there that I can't see and need to wire out to make sure it's clear. Thank you for all your help.
