What carb do you have?
Ive heard of people using tupperware to attach the intake hose of the snorkel. My guess is that the lid of the tupperware goes in between the carb and the air filter attached to the carb while the container part of the tupperware is placed on on top of that enclosing the air filter inside. You can attach a flexible intake hose from the snorkel to a hole you make in the side of the tupperware.
If i have some time ill draw something up in CAD to show you what i mean. Also i would definitely use some sort of microwavable safe tupperware or something that can resist heat.
