I bought a picco .26 engine used. What the guy sent me was a pullsart axle that doesnt look like it will work. All my other engines i have owned have had completely different pullstart axles with a slit in them that grips the crankshaft pin to turn it over. This one looks like some random bolt the guy i bought it from just put in. Please look at the pics and tell me what is wrong. What do i need to buy?

Thanks
