Need starter for Savage X 4.6

[CycoCorey]

Just picked up a Savage X 4.6 the other day. It is missing the fuel tank and exhaust plus the Rotostart (it has a roto backplate). I found everything else but am lost on what I need to start this beast. What starting shaft would I need? If I wanted to go pullstart, how do I know what I need? From my research it appears to be a F4.6 engine (perfectly round purple heatsink, only 2 carb adjustment screws). Pictures attached. Please help. Thank you!

Well I have same engine I was able to put a pullstart off a redcat volcano s30 on my savage. You should be able to purchase a pull start install on your engine. Just make sure the one way hex bearing is the right size for the shaft.
