Alright it's not snug..I don't have to push on it much but it's enough to were that shaft won't grab
 
How much end play are we talking about, the start shaft will have a little, but not a ton.
It sounds like maybe the start shaft or the nub on the crank **might** be worn.
I would pull the engines backplate off and inspect the start shaft and crank end if you had to hold the start shaft in to get it engage the crank.
 
Idk exactly how much play it is but it's not alt cause I barely have to push on it
 
Do you still have the old OWB? If you do, slosh it around in denatured alcohol, rubbing alcohol if that's all you have, and blow it dry.
Thoroughly clean the shaft with alcohol and let it dry. Now reassemble them and see if the bearing only turns one way.
If you tossed the original bearing, do the same procedure I just mentioned, with the new one. When it's on the shaft, reinstall the pull start and test it while holding the engine in your hand. If it's working correctly, install it back in the truck.
 
After doing some digging, it looks like the HPI F4.6 engine's starter shaft is supposed to get pushed into the crank to engage it.
I assume here that the pull start is supposed to push the start shaft in when you pull the cord.
I think it's going to end up being the pull start.
Below is what the F4.6 start shaft looks like.

I do not have a HPI pull start to look at but that's where I would look at.
 
I just realized why it's not working. You're missing a part. In the HPI setup there's a pin on a spring that locks into that groove to grab the crank when you start it.

So we're would that spring and pin be located then? Cause I didn't see them when I took it apart

One end locks in that groove in the start direction, and ratchets when the engine is running. You won't be the first one that missed it.

Page 33, figure 3. Once you have the back plate off it will be obvious.

The pin and spring are very small. When you took off the back plate to change the OWB, they fell out.
 
Well I decided to send the motor in for warranty so they can fix it but thanks for helping me out
