Yeah the pawls come out but looking at it one doesnt come out as much as the others, i might pull the starter apart, degrease the lot of it and put it back together with a light spray of lube instead of the grose grease thats on it.

I havent seen another mower like it joe, and i can find no info on it anywhere.

Will see if the clean up fixes it, will look into the spring assembly too.
