I'm not sure if it's a double pumper or not. Still learning 'bout all this stuff.

Something I found ... The carbs with the end customer 'Crescent Raceway' appear to be alky carbs. There are 4 listed HL194A, HL194B, HL194C and HL264A. I found this quote from another forum. 'Crescent carbs, you may recall, came "alcohol ready" from the Tillotson factory in Toledo.' Just my 2 cents....

Got this from my dad a few days ago. He says it's a rear bumper for an old Simplex Kart. Has anyone ever seen one before? It goes under the engine mount. I remember seeing it on an old Simplex dead axle kart back in the 1960's.
