mystery carb...

[deckerz]

i bought a rc car off ebay about a year ago, it was just for spares really and on the engine it had this carb...



its a little bit of a mystery to me....it has no high speed screw just a twisty thing and has no low speed needle at all.

i need to know what this carb is for not even sure if its for a car, i was thinking its pretty much just like any other carb except you dont have to do anything to the low speed.
