Does a exploded view drawing exist? :confused2:
Iv been told the Vgas carbs are side draft.

Then told they are downdraft by sudco.

Neither drawings look exactly like my Vgas carbs.

I need a accurate exploded view so I can disassemble and clean the carbs. Identify and replace any worn parts and reassemble them before I have them tuned.

Here are a few links I have for fcr's. If you have any other links or info please post them here.

I think it comes out the top and only needs to have the stack removed to gain access.

Somethings going on here. There is a raised ring on the carb body around the slow air jet unlike the #103 main air jet. These rings are slightly mushroomed out and cracked when looking very close. They prevent the #30 slow air jet from being removed. These carbs are old. Probably one of Jons first builds.
 
I think I figured the mushrooming out. One of the PO's before me tried to set the slow air jet with adhesive. Cant wait to uncover whats next.

Question. When using a #30 slow air jet. Is there any adjustment? Or do you need the #129 Pilot air screw and #130 Pilot air screw spring to adjust for instance.. 1 1/8 out?

Thanks

Edit.. Turns out the #30 isn't adjustable. Only the
#129 Pilot air screw and #130 Pilot air screw spring can do this. Yet the PO tried to, by loctiteing it in.:bang head:
