What's this thing in my ebay 2 stroke engine kit?

[jimTheman]

Hey motorized bikers,

I just got my 2 stroke engine kit today. While I was inspecting parts, I found this black, oilly nut and bolt from "bag of goodies". I've watched many YouTube build videos, and I've never seen this thing being used in the build. Does anyone know what this thing is?

That is a crank gear puller- used to get your small bevel gear off.-That's under the right side engine cover- one big bevel- one small one. (carry on) p.s. drive gear also I think. I've not used them yet.

Also for removing the small sprocket.

Also works to remove 3 piece pedal cranks.

Not all of them, would not fit a sickbikeparts crank... Park tool puller does though.

its a popcorn poper. simply place a kernal between puller and the object you need to pull.when you turn the bolt to pull a object off it will compres the kernal thus heating it and then it will pop.
