Where are the numbers on a Demon Carb? Options

[mrtillie]

I have a couple of pics of the carb on my 440. I was hoping to find some numbers on the carb so i could find out what type of demon carb i have?? NO luck. They must be inside somewhere. I found stapled on the drivers side a P and a S which I'm assuming they stand for primary and secondary?? I will post 2 pics of the carb and maybe someone can tell me what model of demon carb it is??
Thanks Garth.

On most carbs,the list numbers and part numbers are on the air horn,or the base plate near the bolt holes.On a carb with no ID marks,you go by the throttle bore size,primary and secondary,and match them to the makers list.This link takes you to the demon site and how to ID the carb,mrmoparthttp:

I just got a reply from Barry Grant. They are telling me this is a Speed Demon Carb. If i send them a pic of the carb from the top view they can tell me what size it is. I will take that pic tomorrow and email it to them.

Now all i have to worry about it feeding this think enough gas to keep it happy lol.
